Thing is, my wrench cleared the codes this morning prior to my 100-mile trek to the yard and back, and they haven't come back on.
Granted, I was driving on eggshells going for maximum MPG, but still... I would think they'd come on if it were something like a gasket leak. I don't know, so here I am.

Yep...
Same experience, as long as I'm a "good boy" with regard to the skinny pedal...nothing.
But when I drive "normally", I would get the same codes. Start with a good maf cleaning...
