Hey guys! My Check Engine light is on. After I installed a WRX muffler on my 2001 RS, I hopped on the freeway and it came on. Gino from MPJ motorsports in Hayward says that the CEL light is the from the clincking in my catalytic converter. There has been noticeable rattling in my cat so can you guys tell me if that would cause the CEL to go on due to the O2 sensors? Thanks!

I have had a CEL in my car for over a year now. Its come on for a bad O2 sensor and after i put in my high flow cat, it is now on for good.

Its not a big deal. If I feel that my car is feeling a bit funny, i take it in to the dealer and ask them to scan it and they can still tell me the problem with it, aside from the cat making it stay on.

Also if you run rich it can kill a cat quickly, causing a rattle and a CEL, go get checked out, good luck man!

Whats making the car running rich?

I have Borla Headers, Weapon R intake and and Pulley in my car. Do you think that makes it run rich? How can I lean it out?
