Thanks guys. Bartman, mine wouldn't work like that because the idle is adjusted at the throttle plate. Now, I suppose I can change that and bypass the throttle body for the idle. Are you saying that there are valves (assuming you have the software to support it) that simply maintain a predetermined idle speed? That's pretty cool, but I just have MS version 1 and I don't think it's that sophisticated. I think I'll go with a GM valve like easy suggested.
