wideband sensor?

I have 2 questions:
1)is it possible to clean the sensor? (mines reading kinda whacky)
2)what are some things that could cause a sensor to foul?

1) maybe... using MAF cleaner... but it will be too late.
2) oil, carbon, silicone, coolant... and anything with water will damage it.

1). You can clean them with electronics cleaner. It comes in a spray can, you can get it at Radio Shack.
2). Backfires are very harsh on Widebands

Thanks for the answers. i think my wide band might be screwed up. I was driving around on a cracked spark plug and i was getting backfires. part throttle and idle doesnt seem accurate what so ever, so i wonder if i fried it/.

I don't know if you are using the LC-1 or not, but if you are, here are the instructions for it.

To achieve maximum precision, the LC-1 and its sensor needs to be recalibrated frequently.
The sensor MUST be operated in free air for calibration.
Remove the oxygen sensor from the exhaust and expose it to free air (outside of the exhaust
pipe) for calibration purposes:
1. Connect the LC-1 to 12V from the vehicle and switch it on.
2. After the sensor has warmed up, either press the pushbutton or connect the calibration wire
to ground for three seconds and release.
3. After the calibration is complete, switch the LC-1 off and wait for 30 seconds before you start
the car.
If a LED indicator is connected to the calibration wire, it will be off during free air calibration.
