Hi all. I have a 95 civic cx. Recently, i find out that there are lot of black smoke come out from my muffler when i try to accelerate. Anyone know why there are lot of black smoke come out from my muffler? thz

 

is the smoke black black, or more of a blueish?? to diagnose what smoke is the source of what problem, use this

White = Burning Coolent... bad headgasket possibly
Black = Car is ruinning rich, not a huge deal just using more fule then you normally would
Blue = Burning Oil, your piston rings are fried

 

I had that problem and it was running way to rich so give it a check.

 

Check your o2 sensor if it's black smoke.

 

o...ic thz! i think the color of smoke is probably black... or white.. i don't know exactly..
i think i need to check how many coolent left. thz all!!
