I had one more sensor to check (O2), I tested the voltage coming from the ECM and its reading around a (.25-.35) I saw the regulation is supposed to be (.5) and it's supposed to fluctuate. What do you think about that?? have I found something?

I'm here for the party
if you unplug it it should go to a default reading of .450-.500mv. it should run better if its disconnected, but i know if it will kick the whole system into "open" mode and read default readings (like when the engine is cold). does it fluctuate when you rev the engine?
