| Just purchased the " Beater" for my grandaughter with 208,000 miles on it. I'm assuming there's a carbon buildup in the engine and the cat. From what I've read on this forum so far Carbon can be flushed from the engine with positive effects on emissions. I was curious if that cleaning action continued thru the entire exaust system (the cat in particular) or does it have a clogging effect on a cat that has high mileage on it and presumably a carbon buildup as well. |
