Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me with model, year and engine info.
By the way, the code 420 may be caused by the misfire, so don't worry about that unless the code doesn't clear after fixing the misfire.
