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.

The linkage bracket cage, bolted to the side of the throttle body, COULD be bolted back on to the TB, such that it's in a
slightly different position, which COULD necessitate the Min Idle adjustment.
