My WK2 has a misfire I cannot fix. For the P0420 I have replaced both o2 sensors. For the P0302 I have replace the spark plug, coil pack, lifters and rocker arms. Along the way this all has fixed something that was wrong, but the vehicle still has a miss. For the P0300, I have replaced all the spark plugs. This is a 2012 2wd with 185,xxx
