Check to see if your thottle plate is carboned uo if it is u can buy a can of top eng cleaner dont do what they say on the can just take the air cleaner hose off and clean the thottle plate the best u can.(if u try to run it it will set a mass air. sen. code)

I have worked on fords for 27 years. There is a screen like or piece of foam
like substance under the pcv valve.It is plugged.You need a special tool to remove it.Then you can clean it or replace it.I Recommend replacing it.See your local dealer for a new one.This will repair this concern.

also take off the idle air control valve and see it the seat is seated when key is off,, then turn key on and see if it moves the pintle to and open posistion,, that will comfirm if it is operating,,,,, u might wanna watch it and let someone else turn the key on for u,,,,,
