Hello! can anyone help me with this?
I have a 2007 Pontiac G6 with code P0303, third cylinder misfire..

Already did the following:
Swapped Plugs
Swapped coils
Cleaned Fuel Injector

*Engine is running fine! no problems running! cant seem to figure this out... The engine light, comes on and off inconsistently once it is reset. Days, weeks... not directly after the light has been reset...

Anyone have any ideas or help!?
