    Still running. At highway speeds, I can feel it stuttering, uphill or under load obvious misfire. No check engine light and no other alerts. Was supposed to drop off at dealer today.. no go. They didn't have a loaner available.

    1st dealer I took it to also said it was interesting that there was no check engine alert. More interesting is that they said it was definitely misfiring. Wonder if they pull up codes that indicate that? And why would they say it was fixed when it definitely is not? Aggravating....

    I've had a couple 6.4s with bad EGR valves with similar symptoms. Studder/hesitation on light accel. No DTCs.
    Did they actually drive it with a scan tool hooked up and monitor for any miss fires?
    To much EGR flow will feel like a miss but usually The pcm will not count any misses.
    Try unplugging the EGR and driving. (The Check Engine light will come on)

    Update..

    So they replaced the head and it seems to have gotten the misfire code to clear. That is a good thing. Still working on the major evap leak. Might have it back by next week! That would be so awesome

    Might as well keep if they are rebuilding your engine, plus warranty.

    Tech I spoke with said he drove it with a laptop hooked up. I believe that's how he confirmed that it was misfiring. Was told all it needed was a, I believe he said PCM reboot? Honestly, on these new beasts, I wouldn't even know where the EGR might be hiding. Let alone unplugging crap and having the dealer say I did "unauthorized" troubleshooting and void the warranty! Just sayin... nowadays, you never know ;) But thanks for the reply and info!

    Update....

    Look like they solved the misfire codes with all the replacements they did.

    It also appears i had a cracked valve on my gas tank that was causing a major evap leak. They are replacing my tank today. I think i will have the truck back on friday.

    I really can’t wait. Been 50 something days.

    You just need the new car scent added and you will feel like you did when you first got it. :)
    Looks like they came through for you and covered some non covered items along the way?! ( not sure what your warranty covers)
