I have changed the engine idle motor and the Temperature sensor without any change. I believe I may at the point of having to change the electronic board. Does anyone have any other suggestions. I know that the engine idle motor is being powered full open and won't close back to the correct position based on what the outside temp.and engine temp. I have jumpered the engine idle motor closed and disconnected it I then opened the manual valve on the air intake which works for now with warm temps. Anyone got other suggestions as to what I should look for.

I don't know the whole story.
The idle valve and throttle switch connectors can be crossed easily. The symptoms will be as you describe. The throttle switch will have an orange, a brown, and a red/white wire. The idle valve wire colors are not these colors and I can't recite them from memory.
