P0306 -Misfire at a specific cylinder should prompt you to check the sparkplug, compression and injector for no. 6
P0300 normally caused by vacuum leaks and bad fuel
Misfires can be caused by worn or fouled spark plugs, a weak spark (weak coil, bad spark plug wire), loss of compression, vacuum leaks, anything that causes an unusually lean fuel mixture (lean misfire), an EGR valve that is stuck open, dirty fuel injectors, low fuel pressure, or even bad fuel.
