Question about Ford Cars & Trucks
What is the idle speed, currently? My tune-up specs don't have idle speed specs because it is computer controlled. You can check and clean the idle air control system. Any applicable trouble codes?
If you think it idling too high, you can block off mouth of throttle body, it should kill the engine. If that has no effect on idle, your getting false air in there from somewhere. Just my opinion.
