AEM wideband issue

Gauge seems to work for the first 10srconds but then pegs out and goes all wacky. I did buy it used. Could it be a bad sensor?

Not the first I have heard of on those doing that. I think if I remember right the last guy called aem and had to send them the gauge.

You check for exhaust leaks? does it only peg out at idle, what does it read while driving?

Test the sensor, pull the sensor out of the bung, spay some carb/brake cleaner in a rag, and then place the sensor in it. if it reads rich then goes full lean you have a bad sensor. If it stays at full rich, then your sensor is good, if it pegs out at full lean while in the rag, then bad sensor
