[QUOTE="tonyt, post: 94857, member: 405"] ok 1 new O2 sensor, from the ac delco guys. it is now reading 10-12mv at idle. gets up to 22-25mv under about 2200 rpm. other, OLD sensor, still reads flat 450mv. unplug NEW sensor and reading goes to 450mv. looks like wrong o2s for sure. now, is the 1 NEW o2 I got producing a VALID signal? a reading that low indicates LEAN condition, right? that does make sense, because it backfired a couple times through the intake this evening, which it has never done before. my question is, should I get ANOTHER o2 sensor like the one I got from the ac delco guys and try it, and see if it totally fixes the problem, or do I STILL have the wrong o2 part number [/QUOTE]
