    My 2002 M40D2 that I bought 2nd hand has a rough idle and what I'd call a misfire/backfire when starting cold. I was just so happy that it ran well that I really had no idea it was doing it until a guy at the launch told me, "Does it miss like that all the time?" And of course I had to reply...
