I just installed my wideband sensor and XD-16 guage and the guage is flashing between 02 and 20.9. Does anyone have any ideas about what can cause this?

it's not calibrated in "free air"??
Get any instructions with it??

is this while it is running or when in the "ON" position. 20.9 is the reading of "FREE" air. after you do the mentioned - free air calibration - then after warmed up you should be able to start up the car and it will give an accurate lamda reading. HTH
 
I calibrated it per instructions (in free air) and it worked fine then I stopped and got out of the car and checked all connections under the hood just to make sure nothing was too close to exhaust heat and all connections were good and when I got back in the car it was doing it. I think I know what happened though. I installed a calibration button in the ashtray and I think when I close the ash tray it pressed the button and it calibrated while running.

I recalibrated it and re-mounted the calibration button and it works good again.

thanks for the replies
