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. |

Onstar can tell you what the codes are, and I'm sure you can look up the codes online somewhere.

Call the dealer and ask if there are any TSB(Technical Service Bulletin) for your car.

If its under warranty take it to the dealer, if its not any scan tool with enhanced capabilities can look at the misfire counter and see if its really misfiring or if there is another problem. It may not be clearing because there are now things called permanent codes that will only clear after the problem is corrected and the computer verifies that is the case.
