All I can think of is that it was raining when I got the CEL so maybe when the wiring for the O2 sensor was lengthened for the LTH's it wasn't made as water tight as it needed to be.

A few of us have been dealing with this code on and off. If you do a search you will see some information out there.

I still have it, but I am willing to bet it is a problem with a gasket from the header to the test pipes and it is leaking. I am just too lazy to take the test pipes out and replace the gasket. I also have started getting PO037 which is the secondary sensor not getting hot enough. Could be the need for a new 02 sensor (although at 12.5k on the car I doubt that), or it could be an issue with the fouler j bend junk on my test pipes, OR it could be a leaking gasket on the testpipe/header.

On of these days I will get under the damn car and replace that gasket. Doesn't seem to effect driving performance at all, so I am not really concerned. I've considered just ordering the osirus cable and disabling those two codes as I can't stand a SES light, period.
