2003 C5 Engine Misfires PO353
Recently been having issues with my engine my car keeps misfiring. I pulled the codes and got PO353 which is cylinder 3 ignition coil. I replaced the coil and drove fine with it. Today i was moving it out of my driveway and it started misfiring again and sent out another code PO 300 for random misfire. Just started it again this time no PO 300 code. I just got this car and checked the oil and saw that there’s way too much oil put into it could this cause the random misfires and possibly ruined the spark plugs?
