Question about 2005 Chevrolet Tahoe

1 Answer

5.3 Litre engine sarts running rough when AC is on & white exhaus

When we turn on the air conditioner, the engine starts missing and running really rough and the white smoke comes out of the exhaust. You can turn off the air conditioner and the problem goes away after a few minutes. Also the cooling fan comes on when the vehicle is sitting still without the engine on and runs the battery down. Do you have any ideals?

Keep getting P0308 code misfire


A misfire code is set because one of three things is missing or not right: spark, gas, or compression. You checked compression and it's good, equal to the other cylinders? And there is spark on #8? That leaves a fuel problem, then. How does the spark plug look on #8- if the appearance is white, almost a blistered look to the bottom of the plug, that is an indication of lean running- not enough gas in the mixture at that cylinder. You may have an injector problem on #8.

2004 chevy aveo when i turn ac on it runs hot and when i turn ac off it cools down


The AC puts allot of heat load on the engine so of course it will run hotter but not overheat the engine, if that happens you may have a clogged radiator.

Air conditioner makes car miss what could cause this


Engine stalling and rough run issue at low speeds

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

1997 lose of power when the a/c comes on


On small engines, any minor performance problem is amplified with the ac due to the horsepower the compressor pulls.
You probably have a spark plug miss or injector problem that is made worse with the ac on.
If you have not done a routine tune-up on the car I would do that first, along with replacing the fuel filter if equipped.
I assume the check engine light has not come on right ?

My nissan frontier runs fine until I turn on the air conditioner, then it begins to run rough.


if it runs rough only at idle with the AC on then it osunds like a the idle solenoid that causes the vehicle to idle up when the ac is on. if its during the entire RPM range then you might want to check your alternator or battery, perhaps one of them isn't supplying enough power to run the engine, lights and A/C

My 1995 Jetta is running fine without the ac on. After I turn the ac on it may drive fine for a while then all of a sudden it loses alot of power and spits and sputters. What could be the problem. Thanks


make sure your plugs and wires are in good condition.also fuel and air filter.the engine has to be well tuned up.because air conditioner compressor put a little load on engine.if engine is not well tuned.the AC will pull it down.cause it to lose power and run rough.
