I do I change a idle control vavle in a 1994 Buick LeSabre?
idle control valve on 1994 Buick LeSabre
The idle air control motor (IAC) is located at the top/front of the throttle housing and has a black electrical connector with four wires attached to it. The nose of the "new" IAC valve must not exceed 28mm or upon installation the "new" IAC can be damaged according to the installation instructions in the workshop manual. Replacing the valve takes just under .5 hours. Simply remove the screws securing it to the throttle housing and replace. Look at www.autozone.com they have workshop manuals on line for free for many popular vehicles or check a company that independent auto repair shops "buy" their information from that offer a very reasonable service to do it yourselvers. You get a one year subscription to year make and model specific repair procedures, service bulletins, component locations, wiring diagrams ect.... great quality information same as the professionals have ,much better than generic workshop manuals from parts stores, much cheaper than the factory manual. http://www.alldatadiy.com/
