Man it kills me to say it, as I have owned mostly Fords in my lifetime, but this vibration @ 55to 70 mph is making me want to look at anything else, even a Dodge or Nissan. May happen soon.

So I'm not sure it this is the place for this but my f150 ecoboost had a very bad shudder and loss of power when accelerating to 60/65 like it had hit the governor or was running out of gas any ideas?

FordService

Sounds like it's dealership time, AK ecoboost. What's your truck's model year and mileage? I'll see what I can do to help.

2011 f150 ecoboost xlt 6.5 bed Kansas City made 43000 miles I have had the slow speed shudder also and have posted the 50 to 55 miles an hour shudder on this before any help would be great thanks

FordService

Thanks for the quick reply, AK ecoboost. I recommend going ahead and getting this diagnosed at your dealership. Once you've had your visit, let me know and I'll be able to research some options to help.

When mine started the interstate speed brake vibration/dance I found both front rotors crackes. Cracking was in straight lines about 1/2" apart runnong from inside diameter brake surface straight out to outer diameter. Egg shell cracking had not happened yet. No build up or frozen calliper pistons. Old rotors gone / new rotors on an brakes drive show room new.

So I took my truck in yesterday for an appointment today at 9am and they called and asked if I wanted my truck back and they didn't even look at it and to bring it back some other time I have had problems with my truck before and had to deal with cal worthington ford in anchorage where I purchased the truck and the only way I got help last time was for a service person from out of state to call them any ideas?

Above is the info asked for from page 1 by OP.

After 2+ years of this thread, what is the verdict?

I have had,
1)reprogram 2)deflector 3)new spark plugs
4) turbo sensor and accompanying wiring harness (this week)

What's next? can I keep this thing or do I need to trade it

Dealer says no new inter-cooler until it throws a code
