[QUOTE="OFFKILTER, post: 1041226, member: 75718"] E Z Fix, No cost. It’s the ideal air control valve sticking because of carbon and gunk build up. My First ST was an o1 4L V6, First started that problem after 175,000 miles. Normally it Idled smooth around 750. Then it started to Idle rough and sometimes not at all. Not a high skill job Just remove the top cover Remove the Two screws, unplug the connection. Remove the control valve (carefully) There is a small gasket, set aside spray the crap out of it until the valve actuates smoothly back and forth with your screwdriver. Then reinstall Don’t forget the gasket. Wouldn’t hurt to spray clean all over related parts and cables. Your ST will idle great. I suggest run occasional fuel injector clearer and check clean or replace air filter too. Sometimes the cause is (Ford said) because using cheap or bad gasoline repeatedly[ATTACH type="full" alt="9B21C731-B0D2-41F1-AE82-5C0F76CE17E2.jpeg"]1737[/ATTACH]. [/QUOTE]
