Factory Truck Cable TB.
My buddy bought it new from GM when he had it in his truck.
Ive never paid much attn to IAC so its probably nothing wrong just what it is.
But today going to lunch i made a log and noticed when i got back in the parking lot and put it in neutral it settled down to the 120s then i killed it.
I lowered my RPMs from 750 to 650 so ill see how it reacts. Then ill take it off and see if its dirty.
