you might try a known good AIC motor/valve.
The idle motors burn the commutator after maybe 150K miles or so. Take one apart and you'll know what I mean. You can clean the valve all you want but if the motor sticks or is bad, it will never hold a good idle.
And yes, you might still have a bad vacuum leak somewhere. check the carbon canister...hard to get to without moving the APC box, really easy if you move the CC vacuum pump but then you have to put the pump back.
BTW..I also had to replace the carbon canister around 200K miles....the valve at the top cracked off.Just old age and heat.
