An update for those that are interested. Mechanic did a leak down test and it showed good leak down on all cylinders. Tried swapping coils/new spark plugs and no improvement so those are out of the equation. Looked at the valve area with the manifold off and no crazy carbon build up as well. Currently, cylinder 2 has been consistently misfiring. He pulled the injectors which is pictured. They don't look too bad I think. The 3rd photo is injector 2. They're off to being cleaned and new seals installed. Possibly switching to e85 dislodged some gunk and clogged the injectors. Hopefully, that will fix the misfires.
