i had a misfire problem with my towncar, plugs only helped a bit i discovered that anti freeze started to leak in and around the boots or the wires, and sorrounding the wires, check all your spark plugs and see if any of them are wet...if so the cheapest way around is using gasket maker around were it leaks or some stuff that stops leaks from say Canadian Tire.
