For proper function of an IAT does it have to have air passing over it or can it just "dwell" in the air. The reason I ask it my new throttle body has an ideal place for it where the idle air control valve used to be but all it has is a passage from the inlet to see incoming air. I will have to block off the passage that goes into the intake to prevent a huge vacuum leak. Will it function properly here or should I just choose another place? I would really like to put it there if possible because it makes the system alittle more modular.
