108k miles and idling rough stalling and sometimes idling at 1200 rpm + and missing. I checked for vacuum leaks and found none. Disconnected the idle control and the car runs great and idles smoothly at 800 RPM. It does idle very low (around 550 RPM) until warm though. Is it OK to leave the ICV disconnected. I am still not sure that it is the root problem. Thanks for your help.
