My car threw p0130 yesterday, which is my upstream O2 sensor, which makes since because i probably did a bad job wiring in my a/f gauge. Im going to by a new one and get rid of the a/f gauge for an oil pressure gauge.

So far, it appears as though bosch sensors are garbage, at least thats the word on here and other cav forums. The odd thing is, when i printed the code at autozone, the kid priced the bosch one for me, and it was a 2 wire sensor, but my car has a 4wire sensor at the upstream (i know becuase i had to wire into it). I've heard the ac delco brand is a good one, are there any others?

Thanks for all you help guys,
Kyle
