Clean the throttle body, too. Have you adjusted the mechanical stop for the throttle plate, or is there anything else holding the throttle plate from closing?
If the throttle plate is held open a bit too much, then the AIC valve wants to close some more to compensate. If it tries to close 'too far' it'll reach that backside opening & the idle will go up. That opening is supposed to be for the limp-home high idle when the AICV is unpowered. I suspect(?) the ECU doesn't really know how to handle that when the throttle doesn't close correctly.
