idle issues still 200

Im getting afraid I may have to go into the dealer and have them use their fancy machine to diagnose the beast. Probly at least $200.

Here’s the issue-Fast idle-way too fast. What’s been done: NEW fuel pressure regulator, changed AMM,. changed idle control thing, changed switch on AMM-NEW. All connections checked. Hoses checked for cracks/leaks and proper fit. Throttle body has been removed and cleaned thoroughly. Computer changed.

Here’s what happens- start up car, idle fine; as I drive along within say about ½ mile idle starts coming up, soon very fast and I mean maybe 3k rpms. IF shut off engine and wait at least 5 minutes, start car, idle usually fine;
but soon starts to come up again. All ignition things, plugs,cap, rotor,all new, oh, and new plug wires.

Thoughts? Thanks.
