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!
