i would like to know if there is a was to clean it other than buying a new one, it has a butt load of black carbon diposit.

my uncle told me to get some marine engine cleaner or I've heard of Mopar Combustion chamber cleaner. You spray that crap into a vacuum hose or in the intake while the car is idling. You'll get all this stuff coming out of the exhuast. It'll clean out your combustion chamber, o2 sensor, and cat. I think you use like 2 or 3 cans of it. When you done putting that stuff in you should let it sit overnight, so you can soak the pistons or something and then fire it up and clean clean clean. You might have to rev the engine while you put the stuff in also to keep it from dying.
