V15 (3rd gear pull) Pull immediately resulted in cylinder 6 misfires and two engine super knocking codes. Car felt like it was going to fall apart and vibrated violently under any acceleration after code came up. Cleared codes and it felt okay after under normal driving.

V14 (3rd gear pull) Replaced both upstream O2 sensors Car feels great, looks like stft %s are better than before changing O2 sensors. Cylinder 2 seems like it still has the most corrections, but doesn’t seem like a concerning value.
