By the way my car has 73k on it.
Are you running a tune? If so, are you maxing fuel trims? I am and I'm trying to see if that is related to the fuel mixture codes or a separate issue. I took my car to the dealer and they smoke-tested both intake as well as exhaust and found no leaks. They also reset fuel mixture adaptations but the codes/SES light came back on within a few days. They want me to put the stock downpipes on before they'll do anything else...so I'm looking for an indy shop that can fix it...stay tuned.
