so the other day while doing a burnout, i was told it sounds like the engine was misfiring.

looking inside the distributor cap, i see there is a fair amount of carbon scoring, sounds like things are jumping around in there.

it is a mopar electronic distributor with the tan cap, and it is vented, and an MSD system.

how do i go about fixing this? is it just possible that the vent isn't enough and i need to drill some more holes in the cap?
