when i started my car this morning i noticed that the rpms fell quick to about 1k and sounded like it was missing. since then i started it again and started its regular warm up idle but i find about 2 feet of black s**t on the ground behind my muffler. last night i threw a map sensor code while driving home and i never turned it off and back on to clear it, i just drove it all the way home like it was. could all this black s**t be there because the code makes my car run extremely rich and since i didnt clear it out while driving it just baked on there over night? i dont want to drive it because it still sprays all kind of black s**t but also it doesnt smoke at all. its a t3 powered z6.
edit: i checked the plugs and they looked like they were running lean. but then i put my hand behind the exhaust and it painted my hand black and wet with gas. im guessing i fouled number 2 since it had the least amount of white on it. when you go to the parts store, you just ask for 2 step colder plugs, correct?
