From experience I'll tell you,,,Take it to the dealer and have it scanned! It can be anything from bad wire connectors or bad wires to one or more sensors out of range. Unless you're rich with a lot of idle time on your hands, get it to a Ford dealer.

Any of factors can effect your idle. Things you can have checked or check yourself, if you feel brave enough are: vacuum leaks, fuel system, egr, pcv, air filter, could be your fuel is not putting out sufficient fuel, head gasket (to my experience, usually not the cause if car properly maintained).
