Anyone ever seen this? Only when you start it up looks like it shoot black carbon type stuff all over the ground. It this going to become a big problem? What does this mean? I am running a Strait pipe with no Cat Convert. Maybe because I have not cat?

 

my integra did the same thing and my cousins hatch does it sometimes too. it's just carbon and water. i wouldnt be worried

 

I thought it was an indication of running super rich?
my ECU went into "limp" mode once(tosses alot of gas to the engine to protect it), and I had to drive the car a long ways to get back home which the whole way it was basically snowing black flakes out my exhaust....

 

....this is b16_madman....

i have a b16a n when i hit it when im up in vtec...i shoot a little suit/black smoke....i heard this if from the oil coolers on the pistons....is it true? if not whats goin wrong.? just a b16 noob

 

Generally Black smoke is an indication of running too rich. Acually I cant think of a case where its not. Black = fuel, so your lucky. Probally not a big deal, mabey a timing issue.

As for black Carbon type stuff all over the ground, I have no idea, but if its any kind of solid coming out of your motor, thats probally not good. Dont really understand what it could be though.

had the same thing with my zc.......dont know what it was

 

could be internal probs, time for a new motor

 

when you first start up your car it runs super rich. almost raw fuel it will dump in if its real cold out. then as it warms up the ratio will get closer to 14.7:1. therefore when its running rich it could be spitting out carbon.

also when i start my car it spits out water with carbon mixxed in it. mufflers tend to trap water when they sit. then when you start the car it comes out along with carbon soot

 

Hey I have a stock DX and I have to clean this black **** off the back of my car every week. It's this black dirt crap that gets all over the back of my hatch. It's obviously coming from the exhaust pipe (duh).

Any ideas what the problem could be? The car runs well.

I couldent have explained it better myself, Good job Dude!
