I have a 2003 f350 with the 6.0 liter Powerstroke and it is running rough at idle and is missing as revved up. I pluggged the scanner in and it pulls code # PO278,CYL 6 Contribution or balance fault. How do I repair the problem and just yesterday I plugged the scanner back in and it pulled the same code ,now its Cylinder #7. Thank you in advance!

Right off the bat without further consultrations, i'd guess seleted fuel injector going weak. can't help but notice it is a 2003 notorious for injector failures.

you repair the problem by taking it to the dealer if you're still under warranty. good luck.

Thank you for your reply and if it were still under warranty I WOULD HAVE DONE THAT BUT SINCE IT ISN'T i THOUGHT i WOULD ASK.

Before you get into it with a wrench, take a voltage reading of the battery while running. the injectors need 48 volts to run and if your battery is low, it could inpact the injectors four fold.
