One other thing I tried was to screw the idle adjustment all the way in to see what happened- nothing!
Appreciate all the help, I am determined to figure this out without taking it to the mechanic!

The air getting into the engine through the intake manifold has to come from somewhere. Metered air can get there several ways. 1) through the throttle at the throttle plate, 2) through the idle bypass passage (idle screw), 3) through the pipe at the Cold start valve. The pipe at the CSV valve connection to the intake manifold is fed by a) the Deceleration Valve, b) the Aux Air Valve, and c) the Aux Air Regulator. If you checked these last three (a,b, and c) per my earlier suggestion, that doesn't leave much. Have you actually checked the throttle plate to see if is being held open a slight amount by something?
