I have an 04 EB Expy with a 5.4. While driving i get an occasional bump or stutter, it doesn't happen while accelerating, or while idling. only while driving at a steady speed on flat ground. if i give it more gas it stops, i replaced the spark plugs (Motorcraft platinum) checked the coils with an ohm meter, changed the oil & filter, trans filter, fuel filter & cleaned the throttle body. It's as if it is trying to down shift from OD but then doesn't.Has anyone seen this? any ideas?
