I've had my 2010 6.4l for three months, but i have put over 10k miles on it already. Sometimes while i am stopped at a redlight or something, it will start missing and running rough. So much so, that it will shake the whole truck. Any clue what the problem is? im gonna drop it off at the dealer monday. really dissapointing.....

 

any luck with this?
I have an 08 that's misfiring hard at idle when warm

 

Mine came out to be a injector had the same problem rough idle
