hmm, i cant see why it wouldnt just be a standard narrowband sensor? If you want a used piece, i suppose salvage yard shopping or FM salvage is your best bet. I like the URG network and there was another that was pretty good, a google search should get you a URG search engine.

I can't explain it but I allways have a check engine light now and my A/F will dip into rich for no reason. I just figure if I can get a OEM one I wouldn't have to worry about it. What's URG?

If you are running rich under cruise, I would suspect either the forward O2 sensor, the MAF sensor, or the fuel system. Note that a genuine rich condition could result in a secondary CEL for the cat or the rear O2 sensor, but in this situation it would be a symptom of the rich condition preventing the cat from doing its job, not necessarily a failure of the cat or the rear O2 sensor.
