    Intake Air temp sensor is located in the air tube off of the air cleaner.

    theres nothing there... in the tube. what is this in this picture? i was told that it was a 2 wire.. but i was curious because it has a vacuum hose going into the tbi unit. maybe to measure the air intake? because this thing is like a thermometer for a car right?
