Cleaned TB, NEED HELP! 700 1990

The IAC has to open when the throttle closes to allow air to enter the engine otherwise it would stall out. When the throttle is opened the switch closes the IAC so that air only goes through the throttle body. Fine idle adjust is provided by the throttle body knob.
