Ok im new to this GN world but i do know a little. My question is, i bought a 1978 el camino with all 1987 gn in it and i just bought a scanmaster, on my scan master it say the air temp is HOT, what does that mean?

It means that its not cold? :crackup:

My guess its that the MAT (Mass Air Temp) sensor is disconected or not present, and its giving the ECM a value that is over 255 - ergo HOT! Either that or things are really getting toasty under your hood...

Perhaps someone more familiar with the ScanMaster can confirm...
