Hey scotty, I have a 2006 Pontiac Grand Prix with the GM 3800 non supercharged, and I have a misfire I cannot get to the bottom of. The codes I have are P0300, and P0300P. I replaced the coil packs, ignition control module, spark plugs, spark plug wires, EGR Valve, and Purge Valve Solenoid. I tested the injectors, and they are all good. What else do you think could be causing my car do display that code and misfire?
