The throttle body can be found with a large wheel and accellerator cable going to it.... which'll move when someone steps on the gas pedal. (If you have traction control, it might be more complicated on this model.)
An idle speed control valve lets air by the throttle body. Once you find the hole you can simply spray down it with a can of throttle body cleaner... might be handy to have that "red straw" to really get in there. Fords have Mass airflow sensors in various wierd places, like the middle of the air intake tube. They're fragile and somewhat necessary for the car to run. To get at the idle speed control, the MAF will probably need to come off.
The best way to clean the idle speed control valve is to remove it and spray down both passages and clean the valve off the car.
The second best way is to run the car while you're spraying through the idle speed control passage. Then the goop that's in there gets sucked through the motor and harmlessly combusted. It may be difficult getting the car to run without the MAF, or you might get lucky and have it idle okay, throwing a code, that will be reversible when you put everything back together.
The third best way is to spray down the hole I described earlier, reassemble everything, and start the car before the solvent evaporates.
Someone who knows fords better should chime in, that's the "generic" way to do things.
Also mention if he has a 4 cyl or 6.
