    may be injector settings were reset after ECM reflashing and you have to off the valve cover and read injector trim codes to change injector settings in ECM.

    I'm in Ukraine. Ok, get DDDL, remove valve cover, wrte inj. codes down a paper and change injector coding with DDDL. Visit any DD dealer

    The first line of his first post is a link to a RAR file with a video clip of the engine sound this is what he's trying to ask you about the engine noise.

    Copy and paste the link into your address toolbar to hear it

    It sounds like it's dropping a cylinder at times and makes me think it losing an injector

    yeah, sounds like missfire. but as I've understood no missfire fault codes, so the problem is in injector coding
