2003 Pontiac Grand Am. My car has a rough idle, stalls and has no power. We changed the plugs, wires, EGR valve, Cam Sensor, Coil pack, Changed oil and added Houes stabilizer, filled it up with High test gas and added fuel injector cleaner. The ICM tested out good at Autozone. We also replace the #1 injector (which was the original code) and checked the resistance on the Crank Shaft Sensor. It was.880. Sounds like the timing is retarded. Any suggestions?
have the same problem?
