Well, then get into all the other factors. . . . the age of the truck, how many miles on the engine? Any mods to the engine? Regular maintenance done to the engine? You haven't given anyone very much to work with.

clean your throttle body and adjust the idle screw . if that doesent take care of it remove the idle control valve and clean it with throttle body cleaner and it should take care of your problem .. it happened to my truck when i first bought it

Thanks-i just bought the truck,figured someone probably ran into it before.
its ur ac compressor its low on freon if it keeps clicking on and clicking off fairly fast

its not the idle screw or air flow sensor if it only does it with the ac on talk to jay or eric at yotamasters just give them a call they should be able to tell u exactly what it is over the phone
