Sorry to butt in-could be the plugs so check when you last changed them and make sure there the approved high performance ones. Also another theory, plug 1 had some rust on it and this was evident when changing the O Gasket cover, so we slowly used uni-abrasive sand paper to take it off, however I done it bc of maintence not misfires.

Once again good luck
