'87 xr7 High idle problem

Tonight after work I crank my car to go home, It idles up as normal but does not idle down. At one point It reached close to 2000 rpm's wile I was leting it warm up. When in gear It was about 1200 rpm's and would not go bellow that. I popped the hood and the checked to throttle body to make sure it wasn't stuck and checked all the vacspooge lines; everything seemed fine. Could it be the Map sensor? Any help would be great. ~Jonathan~

Sounds like your IAC stuck.  Just tap on it to see if it will free up.  If not pull it off and clean it out and have it tested.

I unplugged the IAC and it and the motor didn't idle down at all...

I'll have to take it off tomorrow and spray some wd40 in it. I went back out and cranked the cougar up again and it's not doing it now. The negitive degree temps. outside might be affecting things...:hick:
