So does anyone know if Ford can do a better job at diagnosing my problem. My mechanic had the car for two weeks and ran his diagnostic tool on it and tried a few things and I have tried a bunch of stuff and I still can't figure out what the problem is. I just don't want to take it to Ford and have them try the same things that I have done. I just want it diagnosed and have them pretty positive they know the problem. Is Ford able to do something that most mechanics can't do?

Thanks in advance.
