Any Ford dealership's service department can clean a dirty idle air control valve, if the owner of the car is not comfortable doing so himself. Local maintenance shops are also capable of cleaning the valves if one wishes to avoid the high cost of dealership services.
The idle air control valve is an important part of the ignition system for any car. While most valves will last the lifetime of a car, they are often subject to dirt and dust, which can cause them not to open or shut properly. Special cleaning products designed specifically for idle air control valves can be purchased at any automotive parts store and used at home, or the car can be taken to any reputable mechanic for cleaning.
