That is the Idle Speed Control Motor. Try removing it and cleaning it out with carb cleaner,Also clean out around the butterfly in the throttle bore with carb cleaner and a rag.

no adjustment needed on this vehicle, If it is not idling properly than may need to check for component failure such as a vacuum hose leak or the throttle actuator needs service.

Please run down this guide and report back.
