This magnaflow cat I put on is giving me problems. The O2 sensor is getting bad readings which results in a bad fuel mixture on the diagnostics. So my check engine light comes on. Left my oem cat at parents garage after the install over a year ago and my father threw it away! Does anyone want to get rid of their oem cat? I'll pay premium shipping costs. thanks in advance
might help to mention I have a 2004 3.4L V6 manual 4WD.
I can weld the cat in if I have too.
