I've been having an issue with misfiring on this car. Codes are P0300-P0304. I've changed the spark plugs, air filter, and even reduced the gap on the spark plugs thinking the issue was possibly bad ignition coils. I tested all 4 ignition coils on the car and each produced a nice and consistent spark. The spark plugs from cylinder 3 appear to have possible burning type discoloration on them, but other than that, all plugs are dry and unremarkable. I'm not quite sure what to do. It's my only car, so I can't afford not to have it run. Possibly a head gasket? Is there a way to check that before buying a new one? Maybe it's the fuel injectors? Fuel filter?
Please let me know what you think.
The first codes to pop up are 0301, 0302, and 0300 in that order then the rest pop up with a little drive time. Those come on just sitting in my driveway.
have the same problem?
