Last time that I drove the car (couple of days ago) everything was fine. Fired it up today and the AEM UEGO WB goes through its normal gauge gyrations and then settles on 14.8. It never moves from there. Any ideas? The WB and sensor have only been in the car for a month and have maybe 120-150 miles on them.

 

I had the same thing happen once, turned out to be a pinched wire from the sensor.
