Delayed Acceleration

[adfr66]

Mostly when I turn left, after I get to about 20 mph, the truck does not accelerate for between 20 to 60 feet then it will go on. It does it about every 30 to 50 miles. Has any one else had this problem? What should I do to try to fix it?

Not to be an A$$,But People should Read more before they come on a Site and start Posting threads asking questions that are already being or been talked about :~(

This way we have less New threads about the Same issue ,and all the info and fix's Compiled into One Thread!

There has been a Couple of these issues,It may be related to the drive by wire crap they use today Sure makes you miss The Good Old days i tell ya that!

Considering drive by wire has existed since the 7.3 PSD thats unlikely.

Is it like the tranny kicks in neutral then you get off the gas then its gets back in gear? If so there is a computer update for it.

Well You might be right LOL it was just Something i pulled out my Butt LOL

Actually i feel it would be closer to a ECM issue or something in that area ?

Seems like most of the issues with new trucks is either,The Brain that tells things what to do as in ECM or the sensors that take the readings....To Much Computer Crap on these new trucks if ya ask Me!

I'm starting to wonder if a lot of the "lag/delay" that I hate and people seem to complain about is programing or stategy that Ford is putting in these new vehicles. I was chatting with a friend and he was saying that the new mustangs are just as bad and they are (aftermarket) programing around it. Also a thought is that to keep these truck running as clean as possible, there is a power delay to keep the fueling in line with the turbo spool to eliminate a black puff on throttle tip in. Or maybe a stategy to decease torque in first gear to extend tire life?? (sorry for the rambling)

I can't help but remember all the marketing hype how they changed the intake track to virtually eliminate a throttle lag to end up with a 6.0 lag....and then be told by a service advisor that this is normal....makes me mad.

Our 3 2011 F550 ramp trucks all do it also. I remember reading the marketing claim of no turbo lag to be utterly disappointed with the response on these things.

Take it back to the stealership and let them make it right!

I have the same problem with my 2011 6.7 hesitating. It acts like like a 2-stroke motor with fouled plugs. Dealer plugged into computer and said motor did not throw any "codes", however they reset the computer anyway. Mechanic at dealer said Ford programs a ton of safety mechanisms into the computer so high hp and torque in motor doesn't destroy the tranny between shifts. One week later and truck acts the same way.
