that code your talking about does not ring a bell... are you talking about the IAT sensor? is everything plugged in?
is the maf sensor one of the 85mm? with the built in IAT?
The stock location for the iat sensor is on the right back side of the intake lid "facing the car. It’s small and sticks out a little uses two wires. I can get pictures if you’re unable to find it
The 85mm maf has the iat build in and can be used on the f-body ls1... did you get a harness with this maf and did it have two connections on the harness.
