reset the code and driven the car for a couple of miles and no codes popped up yet so hopefully the knock sensor is not a problem..checked my timing and its at 20btdc..going over my emission numbers i noticed my CO is at 0.01 at both speeds can anyone tell me what that would mean? slow o2 sensor? running super lean??
