Anotger test drive with maf unpluggedverified no hesitation or misfires.
So we definately have a bad maf, as tge problems come right back with it plugged in. Right?
O2 still appears dead though.

Try this:. Go find a 1.5 volt battery, like a AA cell. Figure out the signal and ground wires on the connector at the O2 sensor, and hook a jumper wore to each, with the sensor unplugged. Start the engine, scanner showing O2 voltage. Using the battery and jumper wires, apply 1.5 volts to the harness. Does the scanner read 1.5 volts or close to it?
And: Have you checked the ground wire integrity? Have you accidentally reversed the heater and signal grounds?

Well, it's hard to say anything definitely, but my working process through these kinds of problems is to replace the sensor because it's not testing like it should, and I need to rule out problems one at a time.
It looks like RockAuto has one for less than $40. I would spend that just to catch my own tail.
