hiya guys,

i just had my motor rebuilt within the last week, and have a greddy evo cat back... ive noticed my rear bumper (just above the exhaust) its gets lightly coated with a mist of black stuff... is there an easy fix to get rid of this problem? it would probably be really noticible if i didnt clean it for a week or 2

 

Clean it while it's still cleanable. If you let that smoke build up then you might as well paint your whole bumper black. Just get some Goo Gone and you're straight.

 

I believe this problem is usually caused running to rich. If you have the ability to adjust your fuel, then try to turn it down a little and see if it goes away.

 

arrgh.... i just replaced my wire harness because injector 2 was flooding the cylnder. i dont have a fuel controller. but your pretty positive thats causing the build up?.... im really **** about keeping the car clean... i think i washed my car 9 or 10 times on saturday lol

 

jeez, gonna wash the paint off.
