How to test idle control valve 89 240 200

As Herb said, take it off the car so you can see it and apply 12V to the connector..doesn't matter what side is ground. You should see the 'butterfly close quick through the side hole.
If this butterfly is sticky, I use my fingers to open and close it as I spray some Carb cleaner in it. The car my idle high after install because of the fumes of the carb cleaner.
Also check the Bellows from the AMM to the throttle body for cracks. That will screw up the air/fuel mixture
