Figure I would keep a history while I am resolving my problem over the next few days, in case someone finds this post later and has simliar problems...
Well... havent had time to work on it, other than running a log on a quick drive. This weekend I'm replacing plugs/wires (and doing a compression test [out of curiosity, not diagnosis] since I have the plugs out) and looking for vacuum leak - one known is the valve cover ventilation tube on teh firewall side to the TB - fits loosely in the valve cover hole - which just might be my problem.
Yellow - Vehicle Speed
Blue - TPS angle
Red - Bank 1 Sensor 1
Green - Bank 1 Sensor 2
graph of my O2 sensors in front of the cat. (Bank 1 = front I believe, S1/S2 each side)
For the most part, the red trace seems to look OK, but the green.. you see it hangs up at 800mv. Which means low oxygen, correct?

Eh, well this weekend I hope to track this down...
