Engine Mechanical problem
1998 Saturn SC1 4 cyl Front Wheel Drive Manual
I have a 98 saturn sc1 1.9 single overhead. Cyl 2-3 will only fire sometimes at high rpm. I tried to swich the coils around but still have the same problem. This tells me its not the coils. I would guess its whatever sends the power to the coil. Is there some kind of crankshaft sensor or something? Any input on this issue?
