Basically, you have an idle air control valve and a controller. Of course,
both after thought add on. The controller is located in front of the right
side tail light. It has inputs for engine speed, temperature, AC and power
steering loads. It provides a fast idle for warm up and then regulates it to
stabilize the idle as the O2 sensor system and other loads cause the idle to
fluctuate. It does this by varying the current to the valve. In order for it
to work, you have have all the base line settings properly adjusted.  You
will need to do some diagnostics to sort it out.
