all gears work except reverse, it sounds like it is in neutral

driving home my car had a screeching noise .i drove it home OK but the next morning i had no reverse.the other gears work OK Plymouth voyager 3.0

99 Honda Odyssey random misfire

I have a 1999 Honda Odyssey Minivan with a 3.5l V6 engine. It recently developed a problem with misfiring. I have A misfire code on cylinders 1, 2, 4, 5 and 6 but not on cylinder 3. I changed the plugs, used an ohm meter to check all the coils. All the coils measure the same as far as resistance. I don't know what the actual value is supposed to be. The misfire seems to occur under acceleration, according to the flashing check engine light, but the actual shuddering and jerking seems to happen most during deceleration or braking. The engine misses slightly at idle, but I do not get the flashing check engine light at idle. Also, the van has the usual Honda problem with the EGR port clogging up, but this has happened in the past without causing a misfire. Any suggestions anyone? Please help, I really need to fix this without throwing parts at it, and can't really afford to take it in for diagnosis. I am going to try cleaning the MAF sensor and see if that helps any, will post and let you know the result of that.

GM recalls 475,418 Chevy Cruze for engine shield

General Motors Co is recalling 475,418 of its popular compact Chevrolet Cruze sedans to modify the under-engine shield so flammable liquids are not trapped in the engine compartment, the automaker said on Friday. The recall covers 2011 and 2012 Cruze sedans that were built at GM's Lordstown, Ohio plant from September 2010 through May 2012. The recall affects 413,418 vehicles sold in the United States, 61,299 in Canada and 701 in Israel. Cruze models sold around the world that were made at plants other than the Lordstown one do not have the same design and are not believed to have the same issue, a GM spokesman said. But about 10,000 Chevy Cruze sedans sold by GM's Australian unit, Holden, may be affected and Holden is looking into the issue, the GM spokesman said. The engine shield on the models affected has the potential to trap engine fluids and raise the risk of a fire, GM said. GM said no crashes or injuries have been reported in relation to the issue. Owners will begin getting recall notices in mid-July. A fix of the problem will take about a half hour at a Chevrolet dealership, GM said.

Oxygen Sensors - O2 Sensors

OXYGEN (O2) SENSORS General Information An Oxygen (O2) sensor is an input device used by the engine control computer to monitor the amount of oxygen in the exhaust gas stream. This information is used by the computer, along with other inputs, to fine-tune the air/fuel mixture so that the engine can run with the greatest efficiency in all conditions. The O2sensor sends this information to the computer in the form of a 100–900 millivolt (mV) reference signal, which is actually created by the O2sensor itself through chemical interactions between the sensor tip material (zirconium dioxide in almost all cases), the oxygen levels in the exhaust gas stream, and ambient atmosphere gas. At operating temperatures, approximately 1100°F (600°C), the element becomes a semiconductor. Essentially, through the differing levels of oxygen in the exhaust gas stream and in the surrounding atmosphere, the sensor creates a voltage signal which is directly and consistently related to the concentration of oxygen in the exhaust stream. Typically, a higher than normal amount of oxygen in the exhaust stream indicates that not all of the available oxygen was used in the combustion process, because there was not enough fuel (lean condition) present. Inversely, a lower than normal concentration of oxygen in the exhaust stream indicates that a large amount was used in the combustion process, because a larger than necessary amount of fuel was present (rich condition). Thus, the engine control computer can correct the amount of fuel introduced into the combustion chambers. Since the control computer uses the O2sensor output voltage as an indication of the oxygen concentration, and the oxygen concentration directly affects O2sensor output, the signal voltage from the sensor to the computer fluctuates constantly. This fluctuation is caused by the nature of the interaction between the computer and the O2sensor, which follows a general pattern: detect, compare, compensate, detect, compare, compensate, etc. This means that when the computer detects a lean signal from the O2sensor, it compares the reading with known parameters stored within its memory. It calculates that there is too much oxygen present in the exhaust gases, so it compensates by adding more fuel to the air/fuel mixture. This, in turn, causes the O2sensor to send a rich signal to the computer, which then compares this new signal, and adjusts the air/fuel mixture again. This pattern constantly repeats itself: detect rich, compare, compensate lean, detect lean, compare, compensate rich, etc. Since the O2sensor fluctuates between rich and lean, and because the lean limit for sensor output is 100 mV and the rich limit is 900 mV, the proper voltage signal from a normally functioning O2sensor consistently fluctuates between 100–300 and 700–900 mV. NOTE: The sensor voltage may never quite reach 100 or 900 mV, but it should fluctuate from at least below 300 mV to above 700 mV, and the mid-point of the fluctuations should be centered around 500 mV. To improve O2sensor efficiency, newer O2sensors were designed with a built-in heating element, and were called Heated Oxygen (HO2) sensors. This heating element was incorporated into the sensor so that the sensor would reach optimal operating temperature quicker, meaning that the O2sensor output signal could be used by the engine control computer sooner. Because the sensor reaches optimal temperature quicker, modern vehicles enjoy improved driveability and fuel economy even before the engine reaches normal operating temperature. On-Board Diagnostics second generation (OBD-II), an updated system based on the former OBD-I, calls for additional O2sensors to be used after the catalytic converter, so that catalytic converter efficiency can be measured by the vehicle's engine control computer. The O2sensors mounted in the exhaust system after the catalytic converters are not used to affect air/fuel mixture; they are used solely to monitor catalytic converter efficiency.

lost the keys to my car. how do i get a new one? 1988 Chevrolet Celebrity

you have two options available to you i know because i have done this as well
1. you can get a lock smith you cut you new keys for your car it costs about 40.00 depending on the lock smith
2. you can call your gm dealer give them the serial number and they can get you new keys however you will have to take proof of owner ship to them before they will order it for you
if the car is locked a lock smith can open it for you as well
they usually carry a master set of keys
in a case
i have one of these being that i am a mechanic but now they are only available for certified lock smiths
if that helps

Brake caliper bracket identification Chevy Trailblazer

Subject: Brake caliper bracket identification

Vehicles Involved: 2002-2005 Chevrolet Trailblazer, 2002-2005 GMC Envoy,
2004-2005 Buick Rainier, Oldsmobile Bravada, Isuzu Ascender

Condition: Caliper bracket

Repair Procedure: There are two calipers listed for the above platforms, FRC11237 and FRC11237A.

Both calipers are physically the same except that the bracket is different.

The change to the bracket was made to accommodate the larger rotor diameter.

Caliper FRC11237 will fit most platforms with the long wheel base or with extended cab.

The bracket of the FRC11237 can be easily identified with a protruding tab as compared to the FRC11237A where the tab is even with the bracket.

One other detail is the distance between the mounting holes and the slider pin, the distance of FRC11237 is 3 inches as compared to the dimensions of the bracket supplied with FRC11237A, the distance is 3.250".
