Help me guys

[schroader]

I got me a bronco II. Its an 88 4x4 with 2.9. When I got it, it missed a little bit but I changed pjugs and wires and it quit. But it wants to idle upand down and when you come to a fast stop it will dye. But when you come to a slow stop it dosent miss a lick.. I know its a sensor or something simple but I dont know witch one.

I think it could the the Idle Air controller (IAC) I had this problem in another truck. Quite simple to remedy, its the long round thing bolted to the upper intake on the passenger side. Take it off and get a good can of throttle body cleaner, spray it inside and make sure to get all of the black crap out. Most times that does it. If not there kinda expensive.
