Misfires on one side 3L SCV6 2015

[gclasse25]

Having exactly the same issue. Have replaced many parts, and have achieved improvements, but always show misfire between 900 - 1000rpms !
Bank 2, LTFT is always on negative % numbers, and Bank 1 on Positive LTFT numbers suggesting an imbalance. Im suspecting of a clogged Catalytic Converter.

I you think its the cats or the o2 sensors, try running a bottle of Cataclean through the fuel system. I couldn't believe how much of a difference it made
