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.

Have you checked your oil? Long story short... some have issue with a "full crank"... of fuel. Doesn't run very well then!

I did check the oil before I took it in and it was full and clean.

Go over to F150Forum.com. There are a lot of topics on this issue. Seems like a large % of owners are having the exact same problem, with not much luck getting it fixed. Looks like it might be a trans issue with the solenoids, or engine misfire. Ford better come up with a fix soon.
