sounds about time for a vacuum leak or O2 sensor to break on you. means that the ecu doesn't know how much air/gas is going in so it's guessing all the time--which would account for the roughness. you can tell if the o2 sensor breaks because it's a pain in the butt to get the thing to hold idle after it gets cold.
