Is my wideband broken?

I have an AEM Eugo gauge type wideband that has been running fine for over 2 years. This morning when i drove to work, it was stuck at 14.7. on the way home from work, it was 14.8. I will try to clean the sensor tomorrow and see if it helps, but has anyone ever had this problem before?

probly just need to replace the sensor man. btw use MAF sensor cleaner. those sensors are delicate.

2 years is about all they're good for, especially on a daily driver. You should be able to just replace the sensor for around $50

Delicate is an understatement. I just ruined the wide band connected to my LM1 with some silicone spray. It will work fine for one second and then go way lean and then back. I traced it back to some silicone based spray I used to clean the engine or so it seems. Even so much as the silicone vapors being pulled through the intake will ruin them. I am going to attempt to salvage it but once its fouled its pretty much dead.
