referrs to it as the Idle Air control and also as auto Idle control' The preferred is the Idle Air control which describes what the unit does. it controls the bleed air around the butterfly in the throttle body. more bleed = faster idle less = slower idle. Some times they just referr to it as the control valve. It is the unit which has a large hose which bypasses from the intake log (behind the throttle body) to the front side of the throttle body and has a small connector to the base. To clean remove and clean with some Berrymans or Xylene and blow out until the flapper rotates easily - it will usually be dirty with blacck oily residue and some what gummy - then lube with 20 wt oil upper and lower bearings. shake it around to work the oil into the bearings. While you are at it wipe out the throttle body and spray a little Berrymans inside. re- install and watch it work. your idle should now be stable, if not then some measurements on the unit are in order.
