Although this isn"t a proper fix, and may affect emissions, I ran accross this problem on a friend's 87 2wd wagon.
\015\012There is a dashpot that controls a lever the Idle set screw is on, I am guessing it is a decel valve that closes butterfly when coasting in gear. I never looked at a manual to figure out what controls the vacuum valve that is on the passenger side of the engine compartment, but if you disconect the vacuum line and plug it that lever will not back off and idle will remain where you set it with the adjustment screw.
\015\012Make sure the engine is warmed up and not on a fast idle cam before adjusting idle.
\015\012The car is a 5 speed, I not sure if automatic cars are the same.
\015\012The car idles fine now and still run's great and gets 37+ MPG with 240000 miles!
\015\012If you want to fix it properly you would have to diagnose why that dashpot is being actuated at idle
