So as the title says my car is shooting black soot on cold startup. My carbon canister is not hooked up is it that? Also I get the feeling my car is running too rich.. Any ideas?
its unburnt fuel from poor combustion, the car does not use 02 sensor on start up till it is warm and also the CAT does not work to full efficiency until the car is warm too.. It's when it's blue you should worry.
EG
What is causing the poor combustion. It's to the point that it stains the driveway it starts on
