This is also from the Ford TSP:
PERFORM IMRC OPERATIONAL TEST
* Perform the necessary safety precautions to start engine.
* Apply parking brake and block wheels.
* Key on, engine running.
* Rev engine to above 3500 RPM.
CAUTION:
Keep fingers clear of IMRC lever/cable mechanism.
* When engine speed is above approximately 3500 RPM, both levers should rotate to full open position. At least one lever should contact the wide open stop, the other may be slightly off the wide open stop. This is normal. When engine returns to idle (or below 3000 RPM), both levers must contact Closed Plate Stop Screw.
* Did the IMRC levers cycle from fully closed to fully open when the RPM was above 3500?
Yes
Passed operational test.
