does any1 else have black smoke or had black smoke coming thru the exhaust since and the dealership say they can't find anything??

 

how often does this happen? How many miles do you have on the car?

Is this just revving at idle? or while driving?

 

You're running rich

It's normal

 

^^^what he said....i wouldnt think its normal though.

 

For a stock SS/SC it's normal

They run rich stock.

Just have the dealer flash the most recent PCM for your car and it should be fixed

 

make sure they didnt put 8quarts in a 5 quart engine(or whatever it is)...no seriously its happened before.

 

Your rich bitch!

 

its just carbon buildup

 

well the dealership looked @ it and they say there's nuthin @ all, its mostly when reving high but as well it also does when u just drive around normal i have black smoke and have had it for over a year but it's more noticeable now since there's more amounts.
Just checking to see if other people have the same thing i have.

 

Yes everybody gets it, even when your not on the gas, all GM vehicles have been know to run rich it there stock form, it just keeps things cool and safe! So dont worry about anything its just normal, unless you get a tune to lean it out its going to continue to do it.
