It right where the rubber hose from air filter fits on the intake there is two small freeze plugs about 3/8 in size the bottom one rooted a hole in it

That would be the throttle body. Coolant does pass through that as well.

Ahh see.. now we're getting somewhere. Coolant passes through the throttlebody to prevent icing when ambient temps drop close to or below freezing. If you live in the south and it rarely gets that cold then you can disconnect these coolant hoses and loop them together thus bypassing the throttlebody altogether and solving your problem. But if you live farther north then you need to fix it and one quick and easy solution might be to just go to the junkyard and get another complete throttlebody assembly.

If you are wanting to know the right name of the freeze plug it is called a welch plug.
These are fuel injected engines so there is no venturi in the throttle body to drop the air temp like it was in the old carb engines so you get no icing now. The water though the throttle body is to heat the air so it vaporizes the fuel better.

So.. the icing I have experienced in the winter on these fuel injected motors was a figment of my imagination?

There is not a temp dropping venturi so if it iced up it could have iced anywhere along the air intake tubes.
The Ford shop manuals say water tubes are to vaporizes the fuel better on a clod engine.
I think we have had this conversation before.
