Q: 1994 Oldsmobile Cutlass Ciera stalls after extended driving/ restarts in 20 mins on 1994 Oldsmobile Cutlass Ciera

My 1994 Oldsmobile Cutlass Ciera stalls after extended driving and restarts after cooling. It has a 3.1 V 6 engine and the head gasket was just replaced. I also noticed that it does not like idling for long periods. What could be the problem?

these cars have a tremendous amount of icm(ignition control module) issues that will produce the very symptoms you describe.if you follow the spark plug wires back from the plugs to the coils.and the coils are mounted on top of the module,it is about 8 inches long,4 iches wide ans a 1/4 thick.you can remove it,be careful to mark everything for re-assembly., and take it to any parts store for testing.
