I've been suspecting the tune all along; but, didn't want to go there without checking eveything else.
I'm waiting for a tune now from another tuner to test out this theory. Apparently, I'm pretty far down on the waiting list for a retune though. Still open to suggestions.

The decarb didn't work; but, running a way too lean tune for a few miles seems to have cured the problem. (Read bad detonation on the new tune.
) I put the old tune back in, and no more codes for almost 3 weeks now. Looks like I needed extreme measures to get the carbon burned off.
