I would check the idle air control valve. Might be sticking.


On the wife's rancher it is right on top of the throttle body, held on by two tamper proof screws.


I took them out with vice grips, pull it out, and cleaned it.


If you pull it out, and then turn the key on, you can see it spin one way, then the other. If it gets gummed up it gets stuck and can't adjust.


Clean it so it spins freely in both directions.
