you need to eliminate ALL vacum leaks.
you can check for leaks under the dash by pinching off the interior vac suply hoses under the hood if the idle straitens out you need to go into the dash & find the leaks.
did you try turning down the idle with the air bypass bolt?
& yes on a good aic valve you should be able to move the part inside. with the plug away from you it would rotate ccw & cw I have taken them apart to see how they work & sometimes you cant get them to unstick because you cant get carb clean to the place where the axis is.there are also resistance checks you can do.
good luck
