Hi All

I have a 2002 Chevy Malibu with the 3.1 Engine. When I'm stopped at a
traffic light with the A/C running, I get the worst vibration from the
engine. If I throw the Trans into Neutral the vibration goes away. If I shut
the A/C off it lessens it. What should I look for. The Car runs Great at
all speeds and starts everytime. I've owned this car for about 3.5 months,
the used warranty is about to expire. Any thoughts? suggestions?

Thanks in advance

Larry

What should you look for? The dealer that has the warranty on it.

When the AC is on, the computer tells the engine to compensate for the added
load. All sorts of thing are supposed to happen. A competent mechanic can
easily cure the problem. I can't fix it, but I do know to go to the dealer
if it is a warranty issue.
