My F250 2011 keeps making a knocking sound every once in awhile and seems to miss a little. It is like it is studdering. It seems to be getting a little worse. The problem is that i cant duplicate it and take to Ford.
I am getting frustrated.

Take it to your service manager and document it, write down the date, time, and who you spoke with. Next time it happens, do the same thing.
Most people think theirs is an isolated instance, the more people document it the more attention it receives.
The other point is, if you suffer a mechanical issue, you have documented it. Having a record of dates, times of the occurence will not hurt you.

...might be a bad,shorting(?), plugged injector...sounds fuel related...

Does it tend to happen at low rpm and light load?
