Try cleaning the throttle body. Carbon usually builds up causing the idle air control valve to malfunction. Yes...as the previous answer says. Remove the large oval air housing from the intake and locate the "flapper" inside. This flapper i believe will be closed. Use your finger to flip it open and spray carb cleaner in there and use a rag to remove the black powder that's built up on the inside of the housing. Believe it or not but this slight build up causes the flapper thing to not close all the way! Don't spray a ton, you're only trying to clean where the flapper thing contacts the housing wall.

if the vehicle shifts and drives fine. the most probable cause for this is a high idle. most vehicles idle at around 650 to 700 rpms. when warmed up, check or clean the idle air control if idle is high. good-day !
