PO300, 302,303,305 codes
Today my CEL came on, I scanned it and got the PO300,302,303,305
Random misfire and misfire on 2,3 and 5 cylinder. The car has been running fine. There are no tunes, and the only mods on the engine is a K & N CAI and flowmaster exhaust.
Can anyone give insight? I couldn't clear the codes off either.
