O2 Sensor Code my car is throwing this code causing my car to run very rich. i had cut off the stock cat because it was clogged and it started running like this. so then i put a high flow cat from a camaro the same year. it still throwing the code and still running rich. how would i decode this problem or is there a certain technique to get rid of it? my car is a 1994 A4 Z28.
since changing the cat did not make a difference that may have not been your problem. Maybe the o2 sensors are just not functioning correctly. I do not know how much o2 sensors are for a 94 camaro but for my 93 they were only like $13.97ea from summit for some NGK's. Hope this helps.
