New catalytic converters, still throwing p0422, p0432
Hey all, my car is '99 A6 2.8 QT with 152k.
I have recently replaced the cats (did not replace O2 sensors), the old ones rattled like crazy and I had p0422 p0432 codes.
Good news: car is running great (and quiet).
Bad news: CEL is back on with same codes.
My only other code is p1392 (pending), new cam position sensor in my near future, however I don't think this is related.
I had driven the car for 5 days and about 150 miles before the CEL came back on.
My next guess is O2 sensors, but I have never had an O2 sensor code, and I don't want to throw money at this thing unless I am sure it will help.
Thanks for any tips.
Mike
