I have a new (for me) 2002 GTS FE. It has Corsa Cat back exhaust, high flow cats, Belanger headers, K&N filters and smooth tubes. Now shortly after I got it the check engine light came on and was read out as an O2 sensor in bank 1. The light went off on its own after a day. Now I'm wondering if this is due to the presence of the headers at a much higher altitude and now the computer has compensated for the new altitude.
2nd, as I'm reading about the headers I notice it says not to put thermal wrap on the headers or it will melt/damage the tubing (not sure what tubing). The previous owner hasn't had any problems with the thermal wrap, obviously.
1) Does the altitude thing sound plausible. Would you take it in to have it looked at?
2) Any problems with the wrap on the headers?
Thanks
