yeah the other night me and a couple of buddies where going to some car meet . when i was going to the car meet and heading to the freeway everything seem normal to me then after we got off the freeway ny friend said that a lot of black smoke came out of my exhaust when i enterd the freeway. He told he each time i would shift my gear a dark smoke would puff out !.

Yeah my car is a 01integra ls?>

 

How many miles on motor and any oil consumption?

 

well i got a oil change not that long ago.. well i only have 83000k. yeah i even check my oil and it was fine ?

 

check the o2 sensor

 

i mean the last time i saw my 02 sensor was when i change my header.. they where looking pretty dirty and black. well u think that can be the problem ?

 

yeah i would replace them and then check it out from there

 

umm so it would not be the spark plugs. ?? by any chance ?

 

No check engine light? Are you loosing any oil? Were you mashing on the throttle?

You may be running a bit on the rich side. How to fix this? I'm not sure. I had this

happened to my sedan. Tested the emissions, everything came out fine. It never gave

me any problems.

if you pull you spark plugs see what color they are and i know in the haynes book for mine it show diff. kind of spark plugs and tell you what could be the problem. but it would hurt to pull them and check them out. but o2 are only like $15 at auto zone

 

black smoke is unburnt fuel...

<U> CHECK:</U>
-fuel filter
-plugs
-air filter
-02 sensor (although they only control AF during part throttle)

 

my engine light never came on . my car is running fine.. well yeah the sparks plugs are kinda ashy balck ?

 

yeah i would replace them and the o2 and see if that fixes the problem

 

It should have nothing to do with oil.

Check o2 sensors, fuel filter, cat, etc, check your plugs see what color they are.

edit; i see ppl have already told you that, and you have done it.

plugs dont seem to bad if they have alot of miles on them. replace them and cap and rotor while your at it. and o2 sensors. see if it fixes it, if not take ur cat off and inspect it

 

i still got stock cats on my ride . i havent change it..i need to replace it with a high flow cat !! but to lazy with that !

 

just change you o2 and your problem should go away

 

is your air filter crappy?? Have you been getting bad mileage?? Does your car seem to have less power??

Check those things i listed and you should find your problem....if not, you there is something wrong w/ one of your cats or possibly the EVAP system....although i really doubt the latter
