my friend was drivin behind me the other day and he said my car blowin out mad black smoke. i don't knoe why. my car is bone stock wit 115K miles on it.....i'm pretty new to prelude so any input will be greatly appreciated.

 

most prelude do put out a lot of smoke. its pretty normal stuff. if there is a lot of smoke, then you may want to check gaskets (oil may be leaking into cylinders) or your o2 sensor (causing you to run rich).
