Did a quick search but nothing really. Ive been emitting it appears to be carbon from my exhaust onto my bumper. At first i used to just wipe it clean, but now its starting to really **** me off. How can I fix the problem. Am I running to rich?

And I know the Title is elementary sounding but thats the only way I could describe it. Flame away if you must.

 

Yes you are running to rich.

 

and how do i fix this? also could this be leading to poor gas mileage?

 

get it tuned, check o2 sensors....bad gas mileage - absolutely!

 

and i just threw a CEL 22 code if that makes a difference as well

 

Getting it tuned will help, find out what that code is for. Do you have an adjustable fuel pressure regulator? If so try turning that down some.

 

I get the black bumper too and my car is white

thats gotta really suck

 

Check your O2 sensor, could be faulty.

 

I had a gutted cat and it was too raspy, so I got a high flow one and when I did the change, there was a lot of carbon build up on the o2's, i wiped them off, but not that great, should I go back and clean them out, is there a specific cleaner I should buy?

 

im running a test pipe, but my black soot on the bumper only started after i put my skunk2 IM on. im clueless to how to stop this madness

I used my 3" exhaust for two hours and already my white bumper has black residue around the tip!!! I'll be running a bit rich since I was tuned with open dp.

Here's an idea... a clear coat scrub might help to aleviate the discoloration and excess charanuba wax might help to soak up some of the soot.
