2006 Chevy 3500 High RPM Engine Code P0507

Customers Vehicle: 2006 Chevy G3500 Express (Box Truck)
Engine Size: 6.0L
Complaint: High Engine RPM and Check Engine Light On
Previous Work: New Map Sensor, TPS and Both Upstream O2 Sensors
Problem: Engine is idling at 3,300 rpm and will not idle down

Shop Work Performed:
1) Computer Diagnostics and Scan for Codes
    Code P0507 - Idle Air Control System RPM Higher Than Expected

Possible causes:
A vacuum leak : Leaking air intake after the throttle body, EGR valve leaking vacuum, A faulty positive crankcase ventilation (PCV) valve

Damaged/failed/dirty throttle body

Failed EVAP system

Failed IAC (idle air controller) or faulty IAC circuit
 
We used Brake Wash (flammable) to spray around potential vacuum leak areas and came up empty.  We hooked up a smoke machine to confirm there were no vacuum leaks and test was positive for no vacuum leaks.
 
We removed the throttle body and inspected and found an extremely clean throttle body. While it was of we cycled the key and watched the IAC valve to see if it was stuck. It looked like it wasn't moving as it should... but did move some. With our Scan tool attached, we could see the IAC circuit was not functioning as it should.
 
THE PROBLEM FOUND AND FIXED
 
We then Isolated the IAC wiring from the IAC valve and the pcm and checked continuity and found two wires had none going and if we wiggled the harness, sometimes it would. We found the two wires had broken inside less than an inch form the plug in at the IAC valve, We repaired the wiring by soldering them and tested.  FIXED!!!  Runs great and customer is happy....
 

Chevrolet goes digital at Texas tech-fest

Chevrolet has affixed QR codes on the hoods of cars that, when photographed with a camera phone, will launch microsites with features info.

Chevrolet is making a big splash at the South by Southwest Interactive conference now taking place in Austin, Texas, and it's just the beginning of the GM brand's planned 30 percent commitment to digital this year.

"This is not a nine-day one-off," said Christopher Barger, General Motor Co.'s director of social media. "Everything we're doing here needs to have applications we can build on beyond Austin."

This program is one of the first major social-media and technology campaigns from a Detroit Three automaker other than Ford Motor Co. since the industry took a nosedive in 2008.

But Barger said Chevy's social-media, augmented reality and mobile programs at the conference are not intended to steal the digital-savvy spotlight from Ford. Instead, they're test pilots for Chevrolet, which Barger said plans to commit about 30 percent of its marketing money to digital this year.

Chevrolet is launching an extensive digital campaign at the music, film and interactive festival, including a tie-in with Austin-based Gowalla, where users check in from their phones around the city to get messages and offers from the GM brand. For example, those flying into Austin can check in at the airport for a free ride downtown in a Chevrolet Equinox.

"The reason we're doing this here is so really smart tech people can make suggestions," Barger said of the swarms of digital agency and technology people that descend on Austin every March. "This is a place for us to learn. How do we apply this to the rest of the marketing we'll be doing moving forward?"

Chevrolet has also affixed QR codes on the hoods of cars that, when photographed with a camera phone, will launch microsites with features info. Chevy has also released the iReveal app to view three-dimensional, augmented reality models of cars on the streets of Austin. While none of these programs -- save free rides from the airport -- sound revolutionary, the moves mark a start for an automaker that has fallen behind Ford on digital innovation.

Barger said that while GM has kept its eye on Ford like any company does with a competitor, it's not looking to emulate what Ford has done in social or digital media.
"If really all you're doing when building a strategy is looking to what others have done, you're not going to be successful," he said of GM's plans for digital vis-a-vis Ford. "You need to draw attention to your own brand and find something unique to you."

Chevy has also handed out eight cars for teams to road trip to Austin from all corners of the country, while completing missions determined by Twitter followers along the way and tracking their progress through OnStar and Facebook, though the idea to put people in a car and have them document their experience through social media bears some resemblance to Ford's Fiesta Movement.

BMW to make their smaller cars FWD, CEO says

BMW AG is working on a new front-wheel- and four-wheel-drive vehicle architecture that will underpin a new range of entry-level BMW cars as well as next-generation Mini models.

“There will be front-wheel-drive BMWs in the smaller vehicle classes in the future,” BMW CEO Norbert Reithofer (pictured) said at the company's annual financial results press conference here today.

Currently, all BMW models are rear-wheel drive and all Mini variants are front-wheel drive.

BMW development boss Klaus Draeger said the new vehicle architecture will debut in 2014 with the arrival of the third-generation Mini hatchback.

He said the new architecture will enable BMW to produce a range of vehicles that are between 3800mm and 4300mm long. By comparison, Volkswagen's Fox, Polo, Golf, Beetle and Scirocco model lines fit within the same size range, which covers everything from minicars to subcompacts to compacts.

Sources said that at its peak the new architecture will underpin up to 20 different BMW and Mini model variants.

For BMW, the new front-wheel-drive models will fit below its entry-premium 1-series models, which Draeger said would keep their rear-drive architecture.

BMW needs to meet a growing demand for smaller, more fuel-efficient cars. The company also will have to cope with tougher European CO2 emission rules that start to take effect in 2012.

Reithofer said: "We expect the premium small car segment to grow by 4-6 percent annually until 2020," adding that the group would cut its CO2 fleet emissions by at least 25 percent by 2020 versus 2008 levels, when they were 156 grams per km.

The decision to create a new joint architecture is also a sign of the times. Automakers are under increasing pressure to share investments between brands or with partners to save money.

Obama Motors in Russia Doing Well

Opel workers demanded reassurances that its European brand will not be disadvantaged at the expense of sister brand Chevrolet, after Opel lost responsibility for the Russian region to an Asian arm of General Motors Co.

GM transferred responsibility for Russia to GM International Operations (GM IO), based in Shanghai, sparking fears that Opel could lose access to a key growth market that almost overtook Germany by size in 2008, before collapsing last year.

Opel labor representatives will discuss GM's plans on Monday at a meeting of the Opel steering committee.

"General Motors has not given any thought about what negative effects this decision could have on the negotiations of Opel/Vauxhall with the European governments, since Russia plays a decisive role as a market of the future," unions warned in a flyer to staff obtained by Reuters.

Opel workers will "demand a convincing plan for the Russian business of Opel/Vauxhall be presented (that entails) no restrictions to the market and a further expansion of the sales activities," works council members wrote.

A spokesman for Opel said the decision was made to consolidate key sales and manufacturing operations in Russia and the Commonwealth of Independent States under one managerial roof. The measure would not be to the detriment of Opel, he added.

Nonetheless, German auto workers union IG Metall fears German jobs could be threatened down the line and demanded that GM commit to expanding, rather than limiting, Opel's sales in Russia.

Jilted Opel suitor Magna International Inc. had centered its growth plans for the German carmaker around the Russian market, before GM chose to retain, rather than sell Opel.

Based in Shanghai, GM IO is considered by German unions to be a proxy for the lower priced Korean-built Chevrolets that had earned higher margins than Opel.

A recent decision to build a small SUV in Korea rather than Antwerp, Belgium, was a blow to the Belgian plant, which GM has said will close in the middle of this year to reduce European overcapacity. The Korean plant already makes the Opel Antara mid-sized SUV.

Opel closes 2 key deals

In a separate development, Opel said it reached a deal with unions in Spain over 900 job cuts, a precursor for government aid. The local state of Aragon is expected to provide 200 million euros alone should it approve plans for production in the Zaragoza plant.

Great Britain said on Friday it would provide a 270 million pound loan guarantee to GM, but the U.S. carmaker is still seeking about 1.5 billion euros ($2.07 billion) in state aid from European governments.

"Today marks an important step for the future of Opel/Vauxhall," Opel CEO Nick Reilly said in a statement, thanking the British government for its support.

"I am also grateful for the Spanish government's role in moderating the discussions between management and unions resulting in the important agreement reached early this morning," he added.

Negotiations with Germany remain particularly sluggish, with Berlin's economics ministry saying on Friday GM has yet to update its application for government funding ever since Detroit tripled its commitment to fund Opel's operations.

Electric Modles expected to make up 5% of Audi's Car Sales

Audi A1 e-tron

GENEVA – About 5 percent of Audi's new-car sales could be electric models in 10 years, the brand's technology chief Michael Dick said.

At the Geneva auto show last week, Audi unveiled the A1 e-tron, a nearly production-ready concept developed from its new A1 subcompact.

The A1 e-tron is the third electric car concept from the German brand. Audi unveiled larger e-tron cars at the Detroit auto show in January and in Frankfurt last year.

Audi has already said it will bring an e-tron sports car to market in 2012. A prototype will soon be tested and Audi will head into intensive trials with three to four vehicles by the end of the year, Dick said.

Audi's management board hasn't officially made a decision on the A1 e-tron, but it's very likely that the concept will be built, Dick told Automobilwoche. He expects a three-year development period.

The range of the 102-hp A1 e-tron is about 50km in city traffic. A small single rotor Wankel engine achieves an additional range of 200km. When needed, the engine charges the lithium ion battery like a generator.

Audi is developing components and systems that could also be used in smaller electric cars. For example, the battery cell is the same for both the A1 and a larger e-tron sports car concept.
Dick said that, with its e-tron range, about 5 percent of Audi car sales could be electric models by 2020.

Fiat to pay Brazil $1.5M fine for failing to recall cars hit by alleged hub glitch

Brazil's Justice Ministry has fined Fiat S.p.A. 3 million reais ($1.5 million) for failing to recall thousands of Stilo cars built after 2004 despite an alleged rear-wheel hub problem.

In a statement published on its Web site late on Tuesday, the Justice Ministry said it had decided to impose the highest fine possible under the local consumer law "given that the producer denied the existence of the problem, putting consumers' health and safety at risk."

Fiat said in a statement it would recall the cars to allay consumers' concerns but would appeal against the ministry's decision since it had found no evidence of such a problem in the Stilo vehicles.

Fiat produced 60,000 Stilo cars in Brazil between 2004 and 2008. The Justice Ministry said in the statement the problem appeared not to concern Stilo cars with an anti-lock braking system.

Fiat produces about 700,000 cars a year in Brazil.

injecter cleaners

would it be recommended to run the injection cleaners through the gas tank or should i manually do it

Response 1) I drive a '89 Dakota, purchased new, with 273,000 miles on it. I've added injector cleaner once or twice a year and have never had a problem.

Response 2) I clean my injectors twice a year. However, I know the Complete maintenance history and always use the same brand and grade of fuel. If this is a used car and you have no idea of it's history I recommend that you use a cleaner that goes directly to the Injector/s. These do a much better job than an additive to your fuel. They contain Propane and ARE under pressure. Follow the Directions CAREFULLY! And note, Injectors DO fail. They are an electrical component unless you have a True Diesel. Then they run off a camshaft.



 

Pininfarina, Bollore aim for autumn launch of electric car

An electric car developed by Italian design and engineering company Pininfarina S.p.A. and French financier Vincent Bollore may be available by autumn.

The two European firms initially will aim the Bluecar at fleet customers such as rental car companies and start private sales later. The car will be available as soon as this autumn, depending on the results of crash tests, Bollore said at the Geneva auto show.

Bollore, head of the Bollore group, said two battery plants that have recently been inaugurated in France would each have an annual production capacity of 15,000 30 kWh batteries per year by 2013.

"With this capacity we can make 30,000 Pininfarina cars or 10,000 buses, or 60,000 small urban vehicles," Bollore said. "Our objective is a mix of the three," he said.

Pininfarina CEO Silvio Angori said he expected to ship 2,000 of the electric cars in 2011.

Bollore is throwing its weight behind lithium-metal-polymer batteries -- a different technology from the lithium-ion batteries other carmakers are using.

Bollore said support from Italian banks for Pininfarina meant the Italian company was free from problems. Angori said the group's net loss would narrow markedly this year.

305-hp Mustang rated at 31 mpg on highway

DETROIT -- Ford Motor Co., losing a heated sales battle with Chevrolet's new Camaro, said today that its 2011 Mustang with an upgraded V-6 engine will be the first sports car with more than 300 hp with a highway fuel economy rating above 30 mpg.

Ford said the 305-hp 2011 Mustang 3.7-liter V-6 with a six-speed automatic transmission was certified by the EPA this week at 31 mpg on the highway and 19 mpg in the city.

The 2011 mode goes on sale this spring. Ford says it has about 11,000 dealer orders for the Mustang.

Jim Hall, a longtime industry consultant with 2953 Analytics in suburban Detroit, said the EPA certification of a 300-hp engine that tops 30 mpg is a first.

The Chevrolet Camaro, the Mustang's top rival, is equipped with a 3.6 liter V-6 rated at 304 hp and 29 mpg on the highway. The Lexus RX 450h hybrid with a 3.5-liter V-6 generates 295 hp and is rated at 32 mpg city/ 28 highway.

The Camaro has outsold the Mustang for nine straight months. In February, GM sold 6,482 Camaros while Ford sold 5,115 Mustangs.

Ford, however, outsold GM on an overall basis in February, the first time it had done so since 1998.

Muscle car wars
The muscle car segment has been a historically important battleground for Detroit automakers and one of the only segments -- along with full size trucks and SUVs -- where import brands have not made significant headway.

Ford plans to tout the 2011 Mustang's improved fuel economy during a marketing blitz when the new model reaches dealerships this spring. Ford executives began their pitch to reporters today.
“At no other time in Mustang's history -- for that matter, in automotive history -- have we been able to talk about 305 horsepower and 31 mpg. The Mustang truly is a no-compromises sports car,” Derrick Kuzak, Ford group vice president of global product development, said in a statement.

The Mustang with the standard six-speed manual transmission is rated at 30 mpg on the highway and 19 mpg in the city.
This 3.7-liter engine replaces a 4.0-liter, 210-hp engine rated at 24 mpg on the highway.

Marketing efforts
Amy Marentic, marketing manager for Ford's cars and crossovers, said the automaker's research has shown that fuel economy is one of the major reasons that consumers rule out buying a Mustang.

The marketing campaign Ford will roll out to support the launch of the new Mustang will emphasize improvements in the fuel economy and interior of the sports car, she said.

"The Mustang is a very emotional car but we're going to give people a rational reason to purchase," she said.

GM back on track no longer closing 661 dealerships

GM plans to call representatives of all 661 rejected dealerships by late Monday to notify them of its intent to begin settlement talks, Bunnell said. It will start sending two-to-three-page letters of intent by the end of next week for dealers to sign and return within 10 days, he said.

Dealers then will have 60 days from the day they sign to send documentation complying with requirements in the letter, such as information about working capital, location, licensing, facilities and floorplan financing.

They also will have to return any wind-down money received from GM as they prepared to close by October. Dealerships received between $5,000 and $1 million in wind-down money, depending on their size, Bunnell said.

Once dealers comply with all the requirements of the letter of intent, they can start ordering cars from GM, Bunnell said.

The 500 or so dealers not designated for reinstatement can still ask to be considered for settlement talks, he said. Dealers who prefer financial compensation over reinstatement can request that option, Bunnell said. GM will arbitrate the remainder.

GM's action was hailed by House Majority Leader Steny Hoyer, D-Md.,who was instrumental in getting the arbitration law passed.

Said Hoyer: "It is encouraging news that GM is allowing so many dealerships the chance to reopen without arbitration."
