NO NO... sensor 2 in the back.... my car runs nice right now with euro headers, but I had the SES light for the past 2-3 months first day since I install my new headers and I've tried multiple things and I can't find the problem.
Right now I can only think of two things that I need double check.. the gaskets between the engine and the headers or the right rear bung was not welded correctly and there is a leak. I highly doubt I need a new set of cats.
