Are any of the other ecoboost owners experiencing something that feels like an engine miss when the truck is in 6th gear and accelerating moderately (about 1/4 to 1/3 throttle) between 50 and 60 mph? I have one with 11,000 miles and it's been doing it since around 5,000. I drove a different one today with 3,000 and it was doing the same thing. Mine is in the shop again for the problem. Hopefully the 3rd time's a charm.
