Hello, have a 98 Passport witha 3.2l and 107,000 mi.
Have cleaned TB and all ports including EGR. Replaced
IAC valve, unhooked TPS under PS resivoir. No codes.
Sprayed carb cleaner in IAC port- idle came down, turned engine
off and restarted- got the high idle again. Do I need to drive it and let the ECU
relearn that or not? Only other thing would be Intake gasket that I can
come up with, would I be correct? PLEASE HELP! unhooked neg. battery
cable for 5 min. Idles perfect. Cant figure it out

The engine is finding unmetered air from somewhere. I would suggest a smoke test to find all the air leaks.
