Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
With the misfire coming and going like this here most common in some cases can be a fault with the #6 cylinder fuel injector.I have seen the fuel injector atomize incorrectly off and on like this here causing this misfire.I have also seen ignition coil act up like this as well.
The fuel injector and ignition coil need checked to see which is the cause then replaced from there.In some cases you can swap the injector or a coil to see if the misfire moves.If you do this and the misfire moves to another cylinder then the component you swapped is the cause needing replaced.
This will need tested further though to pinpoint and repair this fault here.
