3.5 EcoBoost Shudder and hesitation
Truck: 2013 F-150 Platinum 3.5L EcoBoost 4x4 with 95k miles
Condition 1: When at steady throttle and speeds ranging from 30mph - 70+mph, if I roll onto the throttle gently, I get a momentary shudder from the motor as it revs up. This happens for less than a few seconds but is easily duplicable. Happens every time I ease into the throttle. If I stomp on it, there's no shudder.
Condition 2: At highway speeds, when I go to overtake someone, and put the coals to it, as I pass through 80mph and roughly 3500-4500rpm, the truck starts to jump as if it is missing.
Condition 3: Randomly, when I come to a stop and then go to accelerate directly after, the truck will delay acceleration, then hit hard. Like a whiplash effect.....
Variables: I have changed fuel brands, and have tested in tow/haul mode, 2x4, 4x4H and 4x4A drive modes. Hot and cold temperatures and high and low elevations.
I hope that all of these are connected to the same issue...but any help figuring it out would be greatly appreciated.

Mine had the bump when gassing it from a dead stop, turned out to be the "F150 bump" This is an easy fix, you need to buy the part from a dealer or even on Amazon. Here is a video that should help. This is the one piece drive shaft but it is very similar with the two piece shaft.
. Here is the part from Amazon. Ford KIT Drive Shaft Boot Repair...

Shudder at gentle throttle

Did you figure it out?? I have the same problem as condition 1!!
