after driving to college the day, the car was very rough and spluttery. it had been raining heavily all nite and it was sitll raining, however I was takin care to avoid large puddles and surface water and where it was unavoidable I was takin my time through it all. Yet the engine sounded like it has a clogged up K&n and burst exhaust. And it died and wouldn't start at lights. Is this water in my carb or in the plugs?
