But the computer should show a history of what the fault was. You need to find out what this is, and then you have a chance of tracking down the problem.
So now you've been to 2 Bozo's that can't even pull computer codes! Even Auto Zone or Advance Auto knows how to read codes for free on top of it all! Learn to look for a real mechanic instead of a lube boy and you just might have a chance!
You can run the codes yourself if you look up how. Too much info how to explain here. Or bring to a dealer. I have a Chevy vette and a jeep. I run codes Myself. I had check engine on my jeep last week. One garage said they could find nothing. I ran them myself and found a battery temp sensor bad even though it doesn't affect engine performance. My vette shows history codes as well as current. Possibly you have intermittent one like I do. Sometimes when you restart your car after it's been sitting the codes clear but still in history. Then I go to restart it and code is back on a week later due to a faulty ground. Sounds like you have a bad ground or a sensor that is intermittently going bad. Good luck
You need a new variable valve timing solenoid. It's a very common problem and most Mechanics don't even know it's there and don't know about the problem. Have it removed and inspected for a deteriorated inlet screen. You can buy the one in the attached picture at any good auto parts store and have it installed.
That's because your "mechanics" can't read the emissions fault code close enough. A Chevrolet dealer can.
If the EML is on then there IS a fault.
and it WILL be logged in the memory.
Suggest you find someone with Ford VCDS diagnostics and not some generic scanner.
