I mean if I have to I can get a tuning cable and block the code. Cause I have a feeling it's why i get below 20mpg avg
This is really aggravating me. I hope after I install the new o2 sensor that it'll just go away but im not sure. the shop isnt liable for the light being back on because I had to bring my own part, not paying 1100 for a new cat from the dealer, better off dumping the car into a pole or ditch. I just paid 300 for the direct fit cat.

There are so many people in Illinois with HP tuners just have it tuned out save a lot of money. And be done with it . No need in dealing with the spark plug fouler it didn't work for me either when I first got my Gxp. but if you want a factory cat and insist on it I still have mine. And BTW yes that is why you're getting ****ty mileage right now
