CEL After 77MM Pro-M?

[Nik_95Cobra]

Hey guys...Unsure why I have a check engine light after installing my new MAF. Yes, it was calibrated for a cobra, and everything's connected, and the battery was disconnected during removal and installation. The meter's a Pro-M 77MM...What Gives? Thanks for the help.

Pull the codes... Does the engine run normally? I am willing to bet it is the IAT sensor.

Threw our snap-on scanner on it this morning and it gave me...157 I think it was...It was a Hard Code. Mass Air Sensor out of range. So aparrently I have a brand new bad meter. Kind of Ironic being that I bought the 77 over the 75 to avoid problems, eh just one of those things...Just a Major PITA since I have to mess with that crap today as well as get my car ready for the show @ the Fun Ford Weekend tomorrow. Guess I'll sit here and wait til I hear back from Pro-M to see what they want me to do.

Before you send it out, make sure you go all the way down the wires and look and make sure none are broken. I would follow the connecter all the way into the fenderwell or wherever it goes. Mine had a problem with the connecter that connects the two meters to the main harness..
