check everything the fonz stated and also remove the air hose from the throttle body, is you throttle plate stuck open a lil.
ford dosent recomend ever cleaning them but if its getting stuck open you have no choice.
a vacume leak is probable but from what you said about the idler pin never touching the metal in its home position, it sounds like 1 either the t.b. is plug up and needs cleaning around where the plate rests, or 2 the throttle cable is sticking.
if that is the case you need to disasembel the upper half of it until you can expose the cable and its casing only.
a shot of wd 40 will smooth it out but not forever. packing grease in thair is the only permenaint cure.
