SE Michigan | Have you tried taking it to a different dealer? Sound to me like (if) you been taking it to the same place they do not know what is wrong with it (?) If you are taking it to a Lincoln dealer only, they may have limited experience with a 3.5 eco. I think if you took it to a Ford dealer they may have a better shot since more Eco's were put in F-150's. Regardless, I would try a different dealer. | |
