fuel content was showing 55% even though I had burned all the e85 out a couple days ago, there was a pending code for the 02 sensor again and lean code for bank 2 I assume the bad bank 1 02 sensor was causing it?
cold start was a bit rough, cleared it out and reset the content, seemed to make a instantaneous difference, I guess I'll see how it starts again tomorrow while it's nice and cold again
