So I finally pulled the engine codes thanks to some people here on the forum.
I got the error code of 72 and 12 (battery one which I dont think is a problem since I had to be boosted not long ago). And 72 being the cat converter failure, my question is, can I just replace that with a straight pipe or a resonator? Or do I need to put a new cat converter in? I know with the OBDII systems, there is a sensor on both ends of it and it would need to be replaced, but I am pretty sure its an OBDI system.
