1997 Dode Caravan - popping noise from engine on acceleration

I have a 1997 Dodge Grand Caravan and I took it to a mechanic and he said that there was low compression in the first cylinder what would cause this and how do i fix it there also appears to be no apparent leak as I have no loss of fluid? I have just recently picked up some K&W Permanent Metallic Block Seal Head Gasket Repair is this something that I should try ? Please help I am desperate as this is my only vehicle and I have four children. Sorry I feel like the biggest idiot i just talked with the mechanic about my car and i was not given all the info as my mother in law was the one that grabbed it for us and relayed the info he said that it was due to a bad valve and that i needed a valve job done on it which is expensive so because when the problem first presented it was making a popping noise so what he did was take off the plug to the first cylinder so it doesn't make the popping noise.

Answer:

The Block seal will not help the issue you have. A valve job or replacement of a valve in the #1 cylinder is eminent. Removing the plug wire from that cylinder will keep the engine from popping but it is important to make sure the Fuel Injector was also unplugged so it doesn't continue to inject fuel into that cylinder and cause the rings to wash out.

1998 Mitsubishi Diamante ES with Check Engine Light. Code is P1400

I have a 1998 Mitsubishi Diamante ES with Check Engine Light. Code is P1400, no other codes. Replaced Manifold Pressure Sensor, cleared codes and re-tested. Light came back on. Check vacuum hoses, connections etc. All look good. Car does not pass following self test for emissions: heated o2 sensor, evap test, purge valve test, catalyst test. all these test show incomplete. Other tests pass. What could it be. Other possible tests and what does the code P1400 mean specifically for this car? Will include bonus if you can lead me to answer. Not a dead beat or negative feedback customer.

Answer:

That code is for DPFE circuit low input. The reason why the other monitors have not run, is because they are being blocked until the other repairs are made. So we need to check the passages for EGR to be cleaned and that the system is electrically working. It may be a defective computer as well or need to be re-flashed.

Now no brake and parking lights

Simple job turned into something major, I hope not. 97 corolla, r. rear brake light not working. Replaced the bulb, everything was working good, decided to replace all bulbs, Antie told me she doesn't remember when they were changed. placed all new bulbs, 1157 for brake lights, 1156 for backup lights. Now no brake and parking lights. Signal and hazard lights are working, I wanted to see if the backup lights worked, guess what, the shifter won't move, like it is stuck. Answer: OK in the process you have blown the brake lamp fuse and this also will affect the shift interlock device. so replace the fuse and see if it blows again or not. if not then great, your back on the road, if so then you have a short to ground somewhere in the circuit.

GM to profit from the Obama bankruptcy plan

General Motors will used the economy excuse to file for bankruptcy on there US business even though GM World Wide is quite profitable. Years ago GM spun off its worst and called it Delphi in an effort to shake Unions and cut costs. For the past 10 years GM has been shutting down plants and moving there companies out of the US to further shake out Unions. Now with The federal government using US Citizens tax money to further GM movement to shut down plants and move more jobs out of the country, GM wants to take it one step further. If GM does carry through with filing for bankruptcy, it may allow them to get out of paying any insurance and RETIRMENT benefits to its dedicated employees. Several months ago GM saw an opportunity to rid themselves of the Contracts they agreed upon and it looks like they just might get away with it. Best of all they can blame it on the Obama Administration for suggesting that is the only way out.

Alternator Repair and Testing

Alternator Repair

Basically this means that an alternator is what charges the car's battery and also provides power to operate the engines computer, lights, radio, etc. So, if the alternator quits functioning then all of these electrical devices will try to run off the car's battery. The problem with that is, once the battery starts to loose power ( since it is no longer being recharged ) the will start to function poorly and will eventually stop running altogether. Generally when the alternator starts to fail a Battery light will illuminate on the dash board. This means the battery is no longer being charged , this does not mean the battery has a problem.

Heater Blower Motor doesn't work in my 2007 Chevy Silverado

GM TRUCK Inoperative blower motor.

The blower motor on some 2007 - 2008 Chevy Silverado and GMC Sierra extended cab and crew cab models built before 4/1/08 may fail to operate. If the fuse is good and the circuit up to the motor has power, says GM, the motor has probably failed. Water intrusion is the likely villain. Installing an upgraded blower motor with a new-design moisture shield (Part No. 25973845) should prevent further trouble.
