I thank everybody for giving me time to think this over and figure it out on my own, but some help would be greatly appreciated!, I'm lost, at least let me know what everything should be running at if you dont know what could cause this!

The way I read that, you're getting a B2S1 code (and not a B1S1 code). Your B2S1 plot looks OK to me. Doesn't look like a dead or dying O2. Got any exhaust leaks?

Ok, you are having a problem with the O2 heating up from what I think at least. With the engine cold it is not following the O2's, hence the closed loop. How is when the engine is at operating temp? What about WOT? You put headers on correct? What brand, and did you double check to make sure the O2 extensions were not that close to the headers. What about swappign out for your old rear sensors?

I've got Hooker shorty's, the car seems to surge just a little after about 40 min. of driving, just does it for a few sec. and I get on it and it goes away, I still have my stock rear sensors in, the pass. side wire is pretty close to the header, its the wire with the heat wrap on it, I'll move that wire further away from the header and double check for exhaust leaks, these shots are from my home pc, just got lap top, I'll update later today w/run logs, thanks...
also, I did get some bad gas, and ses light came on shortly after, wich is when this all started, could the burning of fuel deposits or water in gas cause o2 to malfunction?

I was talking to the guys at TTS after I was throwing heater codes and they said they had good success with putting heat sleeves over the 02 sensors - either the kind you normally use to protect plug wires from headers or the tube type for wiring (DEI makes them).
I replced the 02 sensors and mine stopped throwing the codes, but I will put the sleeves on before the cold weather arrives.
