Problem with LC-1

I have used this fine for over a year, then a couple months ago it started acting up. It would work fine for a few minutes after starting the car, then all of a sudden it flashes 7.4. I just thought it was a loose wire, but now I am trying to datalog and I can't get it to work. Checked all the wiring. Also tried to calibrate it and the gauge won't display the 2 flashing patterns its supposed to or light the led.

Kinda urgent. I am in the middle of something and the car is not drivable at the moment.

Did some searching and found that the sensors are prone to go out a lot on these. Then found out I can get a replacement O2 for it at O'reilly. Gonna try that.

Ok bought a new sensor, now it stays on, but I still can't get it to calibrate. The led won't light up at all. And its reading free air at 21.7-21.8 so I know it needs it.
