New O2 sensor solved the problem ........ I loaded a new O2 sensor, CEL hasn't came back on, and I passed DEQ with flying colors!

Okay, drilled out the non-fouler so the O2 sensor isn't jammed in there so tightly. Got the CEL again, ran the code and now it's only running a P0140 which means I need a new O2 sensor.

I ran the codes and I'm now getting P0140 and P0037, it was P0421 before I installed the non-fouler. So now it looks like the tight fitting non-fouler might causing an error or there's a wiring problem.

I ran the codes and it's showing P0140 and P0037, so circuit low and no activity detected. Could this be caused by the tight fit in the non-fouler?

Thanks for this info, I'll trying drilling the hole bigger and see if that fixes it.

Update: The CEL came on the next morning when immediately upon starting my car. I'm not sure why it's not working, I did everything correct. But it sounds like the things to check are, 1) Is there a exhaust leak 2) Was the hole drilled big enough. It did feel like I had to really cram the sensor...
