Why does a '93 Ford Tempo GL suddenly have a high idle?

Binding throtle linkage or idle control solonoid not working.


With mine it was the IAVC(idle air valve control) on my 94 2.3L Tempo. I got the part used for $10 at junkyard($54 new at Knetch's). On some, the springs stick so you can try spraying it with carb cleaner to loosen them up. Although on mine, the springs moved but you could blow on one end and air came out the other side. On the "new" IAVC part, air wouldn't pass through but fixed the high idle perfectly! Before you take it out, try tapping it with a hammer to see if it temporarily changes the idle any. If so, that is certain to be your culprit for sure! It was mine!
