About a week ago my 08 NA GT was stumbling and running rough. I replaced the plugs, and it ran better, but still had the roughness. On the way home CEL illuminated, and the scanner said P0303 cylinder #3 coil.
Just installed 8 new coils this morning, and it's still running rough with a little misfire. Indeed, I thought I heard a backfire. I stopped and checked, and all the electrical connectors are firmly attached to the coils.
Is there any sort of engine analyzer that would tell me the source of the misfire? Do I just have to wait for a code?
