94 Cavalier RS Rough Idle

My car when in Drive shakes rough, but in Park it doesn't shake. The shaking stops when the car is in motion. It's a 94 Cavalier RS 2.2L 4 Cyl. Anyone have any clue what the problem could be?

i would start by checking for vacuum leaks

also check motor mounts

Thanks I'll check both.

could also be timing. is it ohv or ohc? if it's ohc then crank position sensor could be possible, but if ohv, then timing belt. my wife had this same problem with a 2.2l grand am

Could even be transmission related, TCC solenoid maybe.
