The main problem looks like P0306 which is a missfire on #6 cylinder. P0300 means random misfire so you may have another cylinder misfiring. How old are the plugs?
P0031, P0430 and P2238 all are related to the O2 sensors on bank 1. Which is probably caused by the misfiring of the spark plugs.
I would have the spark plugs changed first. Erase all the codes and then see what happens.
the plugs is about 2 years old what i have to remove on the backside to get to those plugs? a video would help.
