I had my car scanned at Advanced Auto parts, and it had no codes, and the CEL is not on.
like I said, I already did all the basic maintence on it....plugs, wires, cap & rotor, fuel filter, pcv valve, seafoam, fuel injector cleaner
I guess I'll go back and check timing today, as for the o2 sensor....it did not throw a code....but is it possible it's bad?
