 If it's just a random and not one single cylinder, it could be that you've got a leak in an intake manifold gas, especially if it does it. Can you ever feel a misfire, like maybe when it's cold and you start it? No. Okay. Then it's probably not that. But I would definitely check that. You also get lean codes, too, if you're running a manifold leak on one of those or a mass airflow leak.
