isumase

is it coming out like when the engine is runnin or is the exhaust like a black powder cause that could jsut be carbon from you runnin rich

SlowestEJ8

ej2rider

Is the residue oily? How's your oil level looking, is it suddenly going down faster than normal?

Could just be that you're running rich as isumase said. Unless you removed your catalytic converter?

ej2rider

no the cat is on, its stock piping could that and the cat is rusted.... could it be my cat is dead clogin my exhaust making it idle weird?

ej2rider

and yes it is a lil oily

Street Ghost

it's probably running rich. why dont u pull the plugs and check..

ej2rider

i did, and changed them, they were black, how do i fix that

ej2rider

i went from stock that came with the motor, to bosch plat 4's, then went back to stock today when i relized the spark plugs were black

Sounds like it needs rings if there is oily carbon back there, watch your oil level to see how fast it looses oil , will tell you how bad the rings are.

ej2rider

i dont loose oil fast at all, i did an oil change over 3 1/2 weeks ago and level is same

Street Ghost

i wouldnt use anything other than NGKs in my car. do u have the right heat range spark plugs? it's probably just running a little rich. do more mods to the car so it can make use of the extra fuel =P

ej2rider

ok well i took it to my shop and talked to them, and they saw it..... they said start with changing out the wires which im ordering a full msd ignition today lol for the hell of it ha! then if that don't work then it is my injectors which then ill upgrade my injectors haha! so eitherway my motor will be upgrading lol

My guess is that its completely normal.. Its the condensation in the exhaust mixing with the built up carbon in the pipe. And its coming out as a black liquid.

blaze the chemi

I have the same thing. It wipes of easily when it comes in contact with the ground or other surfaces. 95% sure it is just condensation in the exhaust and the engine running rich. Keep an eye of those plugs and borrow a friends wideband to make sure you are running rich, if you don't have one. Do you have a stock uxhaust or do you have a cat back with a resonator? I have the revolution cat back with a good resonator.

umm, last time i checked; you thought you were running a little bit rich. Now why would you want to upgrade your injectors to fix that? the MSD ignition idea was more along the lines of what you should be doing.

ej2rider

idk what the problem is anymore.... it idles like woam woam woam woam woam from 500rpm to 100rpm back and forth and wants to kill when i rev it

bump does ne 1?

postman

the car is running rich, also the surge in your idle has nothing to do with what coming out of the exhaust, check vac lines and pcv

ej2rider

ok well my car dont shoot out black anymore, it dont run rich cause i finally had it tuned and on top of that my map sensor was shot making my car idle and wanna die lol but now the car is fixed and runs awsome!

If the moisture appears to be somewhat like water then that is totally normal. It is a sign of an emissions system fuctioning the way that it should.

The catalytic converter removes deadly HC and the byproduct is water.

ej2rider

if u read it correct it runs fine now, its all fixed

xEnderx

Was the oily black crap coming out of hte exhaus the same oily black crap that was on the plug? Was the plug wet, gooey, or dry?


FYI reading plugs can actually tell you ALOT about the state of the motor. You can get a quick read guide in teh back of any Chiltions manual.
