Question about 1999 Pontiac Grand Am GT
We replaced the throttle positioning sensor in the car, then the plugs and wires and a few days later the car just shut off while i was driving down the road. Now the car won't start. We replaced the coil packs and module and still nothing. When it does start it runs really rough and backfires. Can you help?
Mass air flow sensor made mine start but still is kinda putting
