Hello, my name is***** you for the question. If you have a misfire on that single cylinder and have installed a new cool and plug then you typically either have a failing injector or an internal engine issue. I would recommend that you do a compression test first. If that cylinder is lower than the others you more than likely have a valve issue. If it is fine then the injector may be failing.
