02 Sensor Extension CAT and CEL HELP!
Bought the rx7store high flow cat about 6 months ago now I got a CEL coming on so I had it checked out.
They are saying the cat is already bad but they can put an 02 sensor extension on to help it out?
How can the cat be bad already? and what is the 02 extension supposed to do?
