Turbo flutter on and off - Ecoboost 3.5L 2011
Hi guys,
I have a 2011 EB3.5 4x4. Bought it used.
I noticed that on very light acceleration with a little bit of load the turbo would flutter on and off (for instance uphill - no towing or hauling- at 1000/1500 rpm in 6th gear - 90km/h).
Turbo start and stop (hesitate) until you decide to slow down or frankly accelerate (basically go away from that hesitation range/point). This happen at various speeds but always during light accelerations.
Did this happen to anybody and what I am facing?
Thanks for your

Thanks guys for the hints 
Will look into it - spark plugs / harness -
I am going to the dealership in the coming days for a diagnostic and will get back to you.
If anybody out there has some other observations / ideas about this Turbo issue please share.

I have some good news on this issue and want to share to help any F150 owner that run into the same problem:
I dropped my truck to the dealer and we managed to duplicate the issue I describe in my first post. Ford found the following TSB 13-8-10 that seems to address my issue. This TSB require a reprogram of your PCM (I am not an expert but that's what I understood/find on the web + discussing with the dealer).
I drove the truck for 2 days since my dealer applied this TSB and everything looks good. Truck shift in a more appropriate way and turbos don't flutter anymore.
Thanks Ford and you guys on F150Forum.com
For those of you that are curious here is the TSB description
==================================================
TSB 13-8-10
POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM, PCM)
Description: FORD: SOME VEHICLES, WHEN TRANSMISSION IN 6TH GEAR
AND ENGINE LUGGING UP GRADES AT 15000-2000 RPM, WILL BUCK OR JERK
OR BOTH, SLIGHTLY, AT A STEADY CRUISE. MODEL 2011-2013 F-150. *PE
