    E39 525 rough running

    On the way home today and the normally smooth 525d turned rough. Not too bad at speed but idle very lumpy.

    Took reading on INPA and looks like injector 1 and maybe 2 need attention. reading +6 and -2.69

    going to try injector cleaner first, but before I start looking for replacement injectors any else i should check?

    (no other errors in the memory)
