This. If it were a legit misfire, it would tell you which cylinder was misfiring. You most likely don't actually have a misfire. Also, my experience was not with the stock setup, making that the cause of your problem unlikely.

Lastly, if you're not under warranty don't let Nissan near this one. It's opening up a bottomless pit of diagnostic fees.
