I am wondering if the WB02 is getting too hot in the stock NB02 location? When I installed my Innovate Motorsports WB02 (uses a LSU4.2 sensor) years ago the instructions specifically stated that the sensor should be placed at least 2 feet down the exhaust pipe so the sensor doesnt overheat. I put mine 2+ feet from the Bobs log header in the 3 inch downpipe and have had no issues.
I seem to remember something about if the WBO2 is placed closer to the exhaust manifold the sensor requires a heat sink added to it to keep the sensor from overheating.

Hook back up and let it run at idle till it warms up, if running better, go for a ride and let it re-learn the system. You could have a bad hose on the fuel pump, but try the battery first.
Sounds good I like the sound of that I hope to God that fixes it I'm going to try that right now

I thought I remembered hearing something about reading something about that as well but I guess my question is even if that were the case does the O2 sensor alone have enough authority per the factory tune to make the car run that bad?

One more quick question and this may sound like a dumb question but since the previous owner took out the AC compressor I removed the refrigerant receiver and one or two plugs that were connectors that plugged into it that wouldn't make any difference would it?
