I just bought a 96 saturn sc2. We have replaced the engine, all the hoses, fuel filter, air filter, etc. but it keeps dieing on me when i stop at stop lights or back up and go forward. it stalls four times before i can get out of my parking space. it does fine on the highway but in town it stalls all the time, but we cant figure out what is causing this problem. Does anyone else have any ideas.
