On the misfire I have checked for spark with a spark checker and looks good also installed new spark plugs and swapped coil packs around and code keeps coming back on the same one after erased plug looks little wet when pulled out I would say little oily

If spark was good then next step is a compression test, let me know what readings are. Thanks.
