I am not a tech, just an avid do it yourselfer. I had a similar problem on an 89 F250 (302 with Fuel Injection). Mine was caused by a vacuum leak between the upper and lower intake manifolds. It could be a vacuum leak anywhere (most likely under the hood). You may have to disconnect and block the vacuum lines one at a time until you find the source. I am assuming no one has messed with the throttle body stop screw.
