I have a 2011 F250 6.7 King Ranch with 111k on the clock. Ever since I bought it with 80k miles, power will occasionally cut out for a split second upon initial acceleration either from a stop or when coasting.

Truck has a hypertech programmer but did this before I had the programmer on there and continues to do it whether it's programmed or back to factory so I'm pretty confident it has nothing to do with it.

Fuel filters have been changed recently and did it before/after.

Any ideas?

Thanks. I'll look at the intertube cooler clamps and possibly look into a potential brake switch being faulty.

Any other suggestions would be welcome as well.

 

just a general check of the wiring in and around the power distribution box under the hood. maybe some wire chaffing somewhere.

 

Mine does this too, has done it since I got it, tuner had no effect as it did it with and without. Feels like a gas truck misfire and usually happens at slow speed or when turning and pulling away from a stop sign.

 

Mine has done this ever since it was new - 38,xxx on it now. It always does it when I'm stopped at a stop sign or light, in drive with my foot on the brake. It feels like someone has barely tapped me from the rear. I've never bothered to mention it to the dealer, though, because it only happens every 2-3 months, and they can't even find (won't look for, really) a TPMS error that happens over 90% of the time once I've driven 20-25 miles at freeway speed. (Neither throw a code.)

 

Mine was found to have recorded 783 times when it did this. A new brake switch last week LOCKED all four wheels as I came to a stop about two miles after replacement. Bad switch again. I take it in today to have the switch changed again, plus for them to do a voltage test on the accelerator pedal.

 

Had the brake switch replaced today. Will let you guys know if it solves anything.
