Tore into it today.
The left o2 sensor was actually bad...removed it from car and testing on bench couldn't get it over ~.235mv
Robbed the wideband from my Jeep, and installed that. Datastream looks good now, and appears it is fixed.

Will test drive it later tonight to make sure.
Need to rest for a while. I'm wiped out, I have horrible back pain for over year now...wasn't a fun job crawling around under car & dash.

take the seats out next time you have to do any work inside the car

doesn't take long and saves you a lot of pain

What brand O2 sensors are you using? How many miles on them?

The sensor appeared to be the original with 142k on odometer.
No matter now, the WB is installed and working fine. I replace the other one later, it also appears to be OE.
