  1. P0306 Cylinder 6 Misfire Detected High

    The P0306 code means failed combustion events are concentrated in cylinder six. Like P0305, it only appears on engines with six cylinders or more and usually points to the end of the rear bank, the position that takes the most heat and is the hardest to reach on the whole engine.
