I had same problem...definitely the secondary
valve intake runner problem or thereabouts.....
they replaced an expensive solenoid and it worked
fine.....until I went on my vacation.....I suspect
2nd time around, a connection or something came
loose because computer diagnostics showed no
problem.....Ford never told me if mechanic re-connected anything before testing.....very
frustrating when you KNOW there is a problem and
they can't find it or don;t tell you what the
remedy is....
