seems every 6 months this happens and i can never figure it out.car starts after sitting a day or two-idles fine for like 5 seconds,then check eng. light flashes sending idle to like 1500,then another flash it drops to like 500,then settles down to normal.when its idling high you cant give it gas,it just wont take it,sounds like its gonna die if you do..hmmm...i check for vaccum leaks many times too
 
your IDLE AIR CONTROL valve is dying. Its like a person getting a heart attack or stroke now and then. See if you can get your hands on a CODE reader and check the computer and see if any codes are in its MEMORY. Most likely its your Idle Air Control valve and its gonna need replacing soon. I Have an extra one if you are interested. Latez.
 
im gonna try and give it a quick clean with some throttle body cleaner,it even says safe for fords on the can. ive heard of people cleaning them with some success...ive been informed theyre not cheap either,i havent priced one yet..
