The car has obd0 honda fuel injectors with resistor box. All I rewired were the clips that go on top of the fuel injector because the ford ones are way nicer than the pos honda clips. The car has a airmass header with ractive cat back. I have been running that setup for over a year without a problem. The cel only came on when using the ford clips. I don't see how the clips would throw a cel considering they are just connections and have nothing to do with the resistor box I have wire or the actual injectors.
