under routine tuneup, you dont. engine idle speed is controlled by the ECM automatically. HOWEVER, if during a rebuild of the throttle body, there is a base idle speed adjustment screw that is capped and sealed at the factory. Adjustment of this screw is not usually required. if there is an idle speed problem first check for vacuum leaks followed by a dirty or malfunctioning idle air control valve (this will set a check engine light usually)
