The rough idle may be related to the low compression in cylinder #6. Low compression will continue to cause a misfire until it is corrected. This will cause detonation and timing problems which is what indirectly causes the misfire. I would recommend having an expert from YourMechanic come to your home to inspect the misfiring issue and test the compression, as this could be a sign of a potentially larger issue.
