Me yet again guys. Not sure if i should laugh or cry; this car is killing me. Dealership felt there was nothing wrong with the car. 2 days later, today, I;m driving and I come to a red light after being on the highway for 10 minutes.
The RPMs are down well below 500 and the car shakes fairly violently, in spurts. It feels like its about to quit. Once the accelerator is hit it's all fine again until the next light when it's even worse.
No CEL, full tank of gas, used the antifreeze as recommended...Ive read on other threads here it could be one of a hundred things. Does anyone have a clue or could narrow this down? Ive tried 3 mechs and none have found a problem...
05 Cobalt with 140 000 on it.
Anyway, thanks and happy new year!
