My truck seems to have developed a similar issue as well. When it sits idle for a few seconds, it drops and "shakes" ever so slightly and then idles back up. This just started a week or 2 ago.

Rob, Clean your MassAirFlow Sensor first. I konw you're dumping a oil/gauze filter and that could be the problem. The oil will dirty up the MAF and cause rough idle issues. If that doesn't fix it dig deeper.

Take off your throttle body ( four bolts) and clean it out you'd be suprised how dirty it gets, clean it with some carb cleaner and some rags, and also while your at it take some brake cleaner(electrical cleaner) to your maf sensor ,thats it let it all dry , reset your pcm with a tune, and you should be good
