I have been experiencing "bucking" when the car is in motion after idling at a red light for some time. Advanced auto parts suggests this may be the problem-any others had this?
Vacuum line on 2004 Chevrolet Monte Carlo
Did the auto parts store check for an diagnostic trouble codes stored in the engine control module? If so, what were they? With these codes I could provide better info.
I have a 2004 as well and am having the same issue, I was wondering if you found the problem??
