I OWN A 1999 PONTIAC GRAND AM SE WITH A 2.4 L TWIN CAM. MY #2 SPARK PLUG IS MIS-FIRING ON AND OFF. I CHANGED OUT THE PLUGS, PLUG BOOTS, COIL PACK, CAM SHAFT SENSOR, FLUSHED THE MOTOR, WHAT ELSE CAN I TRY?

Check or replace the plug. Make sure the injector is getting power.

The injector is getting power, and the plugs are new. It runs good if I disconnect the cam shaft sensor.

The service engine light and trac off light is going on and off now. The car is still running poorly
