Do you still have the cleaner in the oil, or have you changed it since? Gunked up lifters may not be expanding/collapsing like they should, so that might be one reason for misfiring. Collapsed lifters under load will definitely give you symptoms like yours. There is a TSB on 5.3's with AFM (Active Fuel Management) lifters collapsing/getting stuck. You can try removing them and cleaning them or just replace them.
