90% of the time it is the coil. The code is P0306? #6 cyl.? If so with the engine running unplug the #6 coil elec connector. See if it changes the way the engine runs. If not then swap the #6 coil to another cyl. If the problem follows the coil it is the coil.
When you swap the coils from cyl to cyl. Try unplugging the #6 cyl coil elec connector with a different coil on it. If it makes a difference in the way the engine runs #6 cyl is ok.
Remember if you rate me we can still continue the discussion.
