Hesitation after quick rolling stops - Ecoboost
I tried searching but couldn't come up with much for the same issue. Too many other hesitation topics...
Anyway, I am having a bad hesitation fairly regularly when I do quick or rolling stops. I will push the throttle to accelerate again and it just falls on its face. I am not sure if it is something in/linked to the transmission shifting between 2nd and 1st or purely engine. It doesn't feel like a missfire. It just like the throttle does nothing for a second or two.
I have brought it up at the dealer, but on a test drive we couldn't duplicate it. I have also reset the throttle by doing the key/throttle cycling.
Has anyone else noticed this and know what the solution is or if it is another "characteristic"?
Thank you.

What gear is it typically in when this happens. Have you tried to repeat it with manual shift mode? I wonder if you are just hitting a spot when the truck is about to downshift, then you apply some throttle and it decides not to shift so it has a short skip before it gets going. If you can put it in M and lock it into a gear and try it, you can see if the hesitation is still there without the shifting being a variable.

Anyway, it does seem to be related to transmission being caught in a not sure what to do state. I am guessing a custom tune would get rid of a lot of the problems I am having, but I just don't want to lose warranty quite yet.

Yes I went back to stock for a short time and that hesitation was very apparent right away. Running a tune for so long I hadn't noticed it for a long time...tune made it go away.

mine does that almost every time, so I would call it annoying, but normal unfortunately.
Part of the issue is the tranny being stuck in 2nd gear, but there is also a noticeable delay when applying the throttle. Like "ok, road is clear, let's go" foot down, maybe 20-30% throttle, 1 potato, 2 potato, might as well bring some bacon, oh there we go... sometimes it will downshift to 1st, sometimes it just moves in 2nd. Of course if you nail the throttle it will downshift and go like crazy, but we're trying to be civilized here
and no, it's not turbo lag contrary to what the dealer said to brush it off when I first mentioned it.
The best way to describe it would be a novice manual driver slipping the clutch excessively... same thing, some throttle but no moving..

Thanks, very glad to hear that custom tuning is able to get rid of this.

I agree with this. My 11 EB was much more responsive. Now, my pedal feels dead off the bottom. I have tried resetting my trans by disconnecting the battery. And it does get a little better. But I think it's the tuning of the DBW that is the biggest thing. This is one reason I have thought about buying a tuner. It sucks, especially pulling out in traffic on a wet road.
