Fires right up and purrs. I'm getting really tired of cleaning all the Carbon build up off the rear end, PLEASE HELP!

i would say you might have a boost leak somewhere try checking that check your hoses for any cracks or bulging and maybe you have bad injectors or yhour amf is bad who kows but check those things out if that helps at all
