This sounds to me like the IMRC box (under the plasitc shroud on the front of the engine) is either not working or the linkage (or cable) is broken somehow.
On my car, I had to replace the box. I opened it up, checked for voltage at the motor inside it, found 12 volts, but the motor was dead. The connector was good.
I bought a replacement unit from Ford parts Outlet (link on main CEG site). It cost me about $110 including tax and shipping. Bill Jenkins should be able to sell you one also for about the same price.
It took me about an hour to replace the unit. [Including a long search for one of the clips that attach the throttle cable to the throttle body.
] [I also recommend doing the work while the engine is cold. You will get a lot fewer burns and scrapes.
