2011+ 55-60mph 5.0 Shuddering and EcoBoost Engine Miss/Loss of Power - Possible Fixes
It never did it before, just started doing it in this frigid weather here (15 degrees). I'll take it to the dealer tomorrow and have them check it. I will not pay for a custom tune when the truck is under warranty.

Others before you have been down this path and have ultimately gone to a tune to fix what Ford won't!
The question that you have to ask yourself is, do you want it fixed, or do you want to *****foot around a largely worthless warranty?Let us know how you make out?
Well, unfortunately I have to contribute to this thread.
My truck: 2012 F1504x4 Crew Cab, EcoBoost. 19500 miles, always serviced at the Ford dealer. Does not have the upgraded intercooler.
Never had an issue until now:
While driving about 55-60 mph, using the cruise control my truck shutters while going uphill. The cruise control maintains the speed and the truck does not shift down, the transmission stays in 6TH gear. No check engine light comes on and the shutter does not happen if I accelerate goibg uphill. I have to say that it is really cold here right now.
Any ideas? Haven't been to the dealer yet and just wanted to know if anybody else had this problem.
Thanks!

My only other thought would perhaps be some moisture in the fuel?
Unless you have a tech that uses common sense, they won't check the plugs. Remember these techs go off of diagrams and computers that tell them what to fix and check.
