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.
 
to add take the 2 screws on the sensor out and pull the 2 pieces apart GENTLY then go to town spraying both

even better try and find a new one at the j yard! cured my erratic idle :yahoo:
