[QUOTE="Race Red Boss, post: 16500364, member: 162573"] My car threw the above code yesterday and indicates a potential catalytic converter efficiency issue on bank 1. Could also be an exhaust leak or bad O2 sensor or wiring. I reset the DTC but still see 3 emission monitors showing red: EVA, EGR and CAT Going to take it into a shop to have them data scan and see if in fact the bank 1 CAT is toast or not. Questions for you guys: 1. How many of you have had a CAT failure 2. If you had a CAT failure, what did you use as a replacement and how did that work out? The previous owner of my car put hi-flow CATs on it....quite a few years ago. [/QUOTE]
