Last week I noticed that past 3k or so I didn't have any power and initially thought it was a problem with the IMRC. Over the week the problem started getting worse to the point that in every gear but first the car seemed to have no power. Then the car wouldn't go past 4k in first either. So to the dealer I go....

...One day later and Ford still can't figure out what the problem is although they've driven it and have confirmed the problem. They have said it's not the IMRC or the fuel pump and I'm at a loss as to what it could be. Appartently so are they. Any insight as to what could be the problem?
