Okay guys i'm really at a loss for words this time. I'm out of all warranty's, past the 5 year mark, and I have been having misfires from my car since the first couple years of owning it. It is a P0303 code that keeps coming back...

2012 Camaro 2LS
51k miles
Swapped coil packs
Cleaned carbon build-up 2x
Valves Cleaned Multiple times
Multiple new plugs
Multiple new injectors
Multiple new coils

3 dealerships ether can't fix it or get it to happen for them.

Got GM involved the last go around.

Thanks in advance!
