Its a 1996 honda civic ex, It just all of a sudden went from running fine to misfiring like crazy... I noticed that the cat was glowing red... So what I've done, got a new cat, new o2 sensors, same codes, which are po301,po303,po304,po1300, So bugging me i went ahead and got new plugs, wires, cap, and rotor, same thing, then a new dizzy, same, new timing belt, timing tenshener, and timed it, same deal, pissed off i went and got a newer motor, and a newer ECU, still the same codes, I'm wondering if anyone out there had an idea of where to go next... Thanks chris.
