1993 Oldsmobile Ciera

Engine Performance problem
1993 Oldsmobile Ciera 6 cyl Front Wheel Drive Automatic

After driving car for like 20 minutes it starts to shake, run rough than stalls. Will idle when in park otherwise wants to stall. I have to keep one foot on gas and one on brake and it sounds like it is on rails.

Has the check engine light come on? Have you checked for vacuum leaks? Have you checked fuel pump pressure?
