Hello. I suggest that you test the idle air control valve operation and check the throttle body for excessive buildup. Both of which can cause erratic idling. At your particular mileage it will be a great idea to have your idle air control valve replaced and a throttle body cleaning service done. You are able to find a technician and schedule an appointment for those services here https://www.yourmechanic.com
