i would check to see if #8 injector is functioning properly. A/F for that cylinder is either pretty rich or lean. check the plugs as well. i know you replaced them, but checking the condition of the plug for that particular cylinder can say a lot. It could be getting washed off by a lot of gasoline, fouled from oil, etc.

I’ll check it out again, thanks for the suggestions
