Daughters 2002 Ford Escape starts but will not

I have the same problem with my 2001 escape V6. there is a really cheap temporaly fix....actually it could be permanent and will never damage your vehicule. When u open the hood there is a plastic guard with the ford logo and engine size that is held in place with 3 bolts, 1 on the left 2 on the rigth. Unscrew these and the guarding comes off. Once this remove you will see the accelarator pedal cable hook to the throttle. U can rock the throttle manually to give more gaz when your motor is running. At the bottom of the throttle there is a small screw that is not touching to anything, if u screw it a couple of turn it will start pushing on the throttle and stop your vehicule from stalling. Adjust this screw until your RPM indicator on your dash board is at around 600 rpm wich is the normal idle speed of your motor when functionning normaly. The real problem is an air intake valve that is defective (150$) because it open when the vehicule starts but shut because defective causing your engine to stall because no air for combustion....By forcing the screw on the throttle the valve cannot shut down and that is why your vehicule wont stall........It takes a full 5 minutes to do the mechanical screw fix...And I drove one year on it before replacing the valve........good luck from a friendly canadian........
