[QUOTE="crash2, post: 1261278, member: 15940"] The correct method to setting min air rate(AS per GM specs)---key on and ground A&B on the aldl. You should hear the IAC buing(trying to close it). At this point you need to disconnect the iac. Remove the ground wire from the the aldl and start the engine. You need to set the rmp to 450-500rpms at the set screw on the throttle body. Some systems have a problem trying to reconie where the IAC sits after this procedure. What I do is key off-hook up the IAC--key on and again ground the aldl--this will drive the IAC closed again--but will also give the ecm reference to where it sits since that system is a non feedback for the IAC(computer does not really know where it truely sits. So at this point remove the ground at the aldl. Start it. At this point I like to see the data and make sure the IAC counts are roughly around 15 counts. If its off--you might need to "slighltly" tweek the min air rate screw.. [/QUOTE]
