Subject:      oxygen sensor problems
Content-Type: multipart/alternative;

Hi

I just replaced my muffler. In the process I removed the catalytic pipe and disconnected my oxygen sensor plug. I cleaned up the various joint services and installed new gaskets and bolts and put everything back together. I did not remove or mess with the oxy sensor itself. other than looking at it inside the cat pipe. I plugged the oxygen sensor jack back in and went for a test drive. initially it ran fine ( I guess that is closed end loop) but when the engine started to warm up then my performance went to hell. I disconnected the oxygen sensor plug and could drive home with good engine performance. previously a mechanic had told me that my oxygen sensor is getting lazy and that I should replace it soon. I am planning on doing that soon but in the interim I can't figure out why a new muffler install would cause such problems with the oxy sensor. it was working relatively fine right before the new muffler.

thanks for any help
