Ive heard nothing possitive about the Accel coils so if you havent replaced the plenum yet I would replace those coils.As far as the slapping noise,a miss will get the DM flywheel jumpin around and just might get the cam chains to make a racket.When I had an injector die I got a noise that sounded like a rod knock but knew it was the flywheel.
