Does anyone know the number of turns the idle set screw on the throttle body should be at? I'm working on this car that is set 2.5 turns out from throttle being completely closed, in other words I backed the screw off until it didn't touch anymore, which was 2.5 turns, so throttle plate was all the way closed, then turned 2.5 clockwise which opens the plate slightly. The tps voltage at 2.5 turns is .7 , would this also be correct. I'm chasing high idle, then stalling problem. Thanks
