Even though the cable is mostly the culprit, I would still lubricate it along with the throttle body shaft. You may also want to take the throttle body out / off and clean it inside where the butterflies are. They may not be seating properly. Then I would check for the idle speed microswitch for operating properly electrical and mechanical. Then if it is working ok then check the idle speed motor for sticking and the connections. John Hervey www.specialTauto.com << I have a question based on my idle. (I have an 81, 5 speed) When I start the car it idles as normal (after an initial high idle and then kick down in a few seconds). As I drive and stop the car seems to idle fine. After about 20 minutes of driving when I come to a stop the car wants to idle at 1500 - 2000. If I blip the throttle it does not seem to make a difference. If I rev the engine up close to red line and let it fall down it tends to drop to around 1000 RPM ( a little high still but better). I have opened the engine bay during one of these high idle sessions and pushed on the throttle and it did not make a difference so I do not believe it is based on a sticky cable or such things. What may be causing this? >>
