I've been getting a lot of buildup of black something on my bumper around the exhaust. So, I must be running rich... I changed the plugs about a month ago, and it ran good for about a week. I've been washing the rear of my car about every two days so it doesn't get too bad, and it's getting a little tiring. Any ideas on what could be causing it, or what would cause the plugs to foul so quickly? Any help is appreciated.
