hello out there, so my girlfriends stang is having some problems. whe i went to start it this morning it idles up to 3200rpms and stayed there when it was in park. as soon as i put t in drive it went down but still to 1500. i hae checked out the throttle and all the fun stuff. nothing sticking or anything like that. i have heard that the throttle position sensor goes out on the 90's models. but i didnt think it would make it idle like that. i was also thinking a vacuum leak. i dont have an obdII reader so i cant check any codes nor do i have money for one. i need to t this fixed its our only car. any input wold be great thanks!

Remove the IAC sensor on the side of the throttle body and clean with carb cleaner. You will need a gasket. Motorcraft will want $20 and they are not at the parts stores. You can make one or pick one up at sites like Latemodel Restoration Supply - Mustang Parts, Chevy Truck Parts & Dodge Challenger Parts

You may also want to inspect the inside of the throttle body and clean out any residue. Do not use carb cleaner inside the throttle body as it may remove a coating that is supposed to prevent build up of gunk.

These are the top 2 most likely sources.
