Not solved!!!

I took it out for a drive and could barely make it around the neighborhood. When giving it gas, the short term trims were pegged at +25% and eventually the long term trims settled above 30% again.

Midway through when idling I was seeing:

STFT1 -19.53%
STFT2 -19.53%
LTFT1 +21.88%
LTFT2 +20.31%

Maybe a fuel delivery issue??
