02 sensor wire harness?
Ok I replaced my 02 finally passed emissions. Now my problem is it runs like crap until it warms up. I have reset the ECM 6 times. I had a broken wire on the harness that I repaired with solder and a shrink tube. My understanding is the 02 has a heating element that kicks in until operating temp. Anyone know which wire this is. I checked Haynes with no luck. I assume the broken wire was to the element causing my cold running issue and I need to repair my repair maybe cut it back further for a cleaner connection.
