I have a 97 Gr Am GT 2.4 and have had a bucking problem on acceleration. Idles fine and runs well when not bucking. Garage has changed 02 sensors, EGR, throttle body and TPS. Ck Eng lite clears for a while then after few miles, trouble starts again. Going crazy and running out of money..... Any ideas ?????

The 2.4L engine in that car has some sort of crank case vent/EGR thing that clogs up. Get the codes read so you know what is causing the light. Head over to GAOwnersClub.com to find out about the vent cleaning.

Check the motor mounts. Bet one of them has separated.
