when the engine is cold it should idle faster and as it warms up it should return to normal.

once it is all the way warmed up you should be able to block off the passage in the throttle body and not see a significant change in idle speed.
What Passage On Throttle Body Do You Meen, Are You Talking About The Coolant Lines That Hook To It.thanks
