White is fuel or water, black is probably egr, blue is oil, brown is a shart.

As cartmanea stated this is simply a prime example of "excitment of the bowel" caused by the adrenaline rush when stomping the pedal....which results in said person sharting!...Simply embarrasing but it does happen.....lol

Depends on how its over fueling. Black smoke on throttle romps can be unburned, excess fuel (not enough exygen, but too fuel spray). White smoke that smells like fuel (usually at idle) can be from a leaky injector dumping in excess, poorly atomized fuel. Black smoke EGR related is from too much EGR flow and not enough oxygen, causing fuel to not burn.

Well, I have a feeling this statement might induce such condition if one reading this thread laughs one's self to the point of......nevermind.

But seriously, brown smoke? I guess that black smoke may appear to have a brown tinge to it depending on the background setting, but I don't know.

How 'bout a vid?
