Q: 1997 Saturn

asked by on October 06, 2016

Coil packs getting fire. Runs rough. Backfires when I step on the gas pedal and no power and the service engine soon stays on flashing? I've replaced plugs and coil pack reset the SES light but it still does the same thing. Is it the crank position sensor?
