Question about Ford Thunderbird

1 Answer

High Idle I have a 1993 t-bird that ran great till a few days ago. I was a little warm so I turned the AC on. When I got home and put it in park the Idle was around 2200 RPM. Turned everything off and still high. On the short, I have replace the IAC and TPS. Still runs 55+ mph with overdrive off. I did hook a OTC genisys to see what codes might be ( due to no check eng light) When I started the car it ran smooth..Unhooked the scan tool and the idle went high again..............I have been a Tech for 26 years, just never messed with fords much.... Problem is I have to drive this one everyday. Any help would be appreciated
