If you didn't break the adjustment on the throttle stop, that's probably not your issue. I would do what you have to to read the IAC count value on your data stream. (or pull the IAC plug as suggested above).

Lets not make it complicated beyond that. There seems to be a fundamental air leak. it is often suggested to take a stiff binder book cover or similar and block off the air horn (accordion duct removed) while the engine is idling to try to stall it. if it still runs, you can often hear the point of the air leak under the plenum.
