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.

So even though i have bought it used from another member here i can still use the warranty on it?

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

It doesnt matter what im doing it does this


that was getting on the highway, it will also do that when im idling, it reports right for the first 5-10 seconds of being started then it goes crazy

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

otherwise you have a wiring issue with where you ran the 12v or the ground wire

Wouldn't be a wiring issue, i tapped into the head unit harness for that and confirmed with the volt meter. i will probably try the carb cleaner in the rag tonight when i get home
