 Bought van 5 years ago with around 50000 mi.  77000 on van now. Started while under warranty with check engine light had intake gaskets replaced and after warranty out same problem. Replaced o2 sensors and still have intake manifold leaks.  Tranny out now. Suprised ford not richer with what they are selling. No help for the working guy. I also had door switch replaced at my cost. Good luck if you have one.  Still debating on fixing tranny maybe I should get out while the getting is good
