This is a bad throttle position sensor

I believe there are two fast idle cam valves in this vehicle.Only been several years since I've repaired one. One for the winter and the other for the summer. Your gonna need the shop manual to determine which one is which and where they are located. Now you said its fine "cold" so its the summer one. Short a shop manual what I would do is they are probably on the fire wall as close to the throttle body as possible. There should be two small philips on top of each one holding down a small plate. One at a time remove the screws and plate clean them out with a rag dipped in carb cleaner then squirt a drop of oil in one of them and close it up. Start the vehicle let it run and see what happens. If the symptom goes away you found your culprit now replace it. If it didn't work do the same on the remaning valve and see what happens. Again if the symptom relinquishes its the one you have to replace.The fix for these valves is replacement the squirting of the oil trick doesn't last that long. Good luck

It may be caused by a vacuum leak, make sure to check all your hose for cracks and/or hoses that may have popped off

check for vacuum leaks around the intake
