[QUOTE="Fred W, post: 1115935, member: 3828"] My guess based on your brief description of the issue is that (one or more of) the 4 fast idle pistons in the throttle bodies (that move to open up the fast idle air bypass) are somehow stuck in the closed position such that the wax motor (or your fingers) is unable to move them to the open position. With the engine warmed up you should be able to push the fast idle mechanism and see the pistons open and close a little (will be hard to close them against the cold wax motor). Also, be aware that on 2nd gens the fast idle is adjusted so that the high idle is not that much higher than warm idle, as contrasted to 1st gens where the high idle is ~2500 rpms. [/QUOTE]
