Could be too much fuel being burned. Gunk is building up, and when the engine is reved, the build-up is forced out. I have the same problem, and black spots all over the wall in my garage. Running rich sounds right. Best to get it fixed before you develop converter problems. Your fuel economy will improve dramatically. Do you have a check engine light on? If so, get the code read to you, and it's possible that you have a bad 02 sensor, I had the same thing with my 96 Explorer, replaced the 02 sensor. A few minutes after replacing the 02 sensor, I blew the rest of the carbon out of the exhaust, and havent seen it since.
black is excess fuel
No. A bad head gasket would cause water to come out the tailpipe. You will see white smoke. Leaky rings would cause oil to come out the tailpipe. You will see blue smoke.
Head gasket or cracked head
Black smoke usually means the engine is running too rich. The fuel/air mixture is incorrect. Blue smoke is oil burning.
Excess fuel causes black smoke.
Need to know why this is necessary.
White smoke is a symptom of a blown head gasket.
Blown head gasket. Or a missfire cause by a bag ignition coil, fouled plugs, too little fuel pressure, timing is off ect.
It could, depending on the cause of the misfire.
my guess would be bad piston rings
blown head gasket!
the only thing crossed spark plug wires can do is cause one to misfire.
No, the engine exhaust is what comes out of the tailpipe.
Blue smoke is burning oil.Blue smoke is burning oil.
I would say no. It sounds like water is entering the combustion chamber from maybe a bad head gasket.
The same thing as on lesser cars: Black smoke means either you're running WAY too rich - unlikely unless a sensor is screwed up in your fuel injection system - or you're burning oil. And the main reason you're burning oil is your piston rings are shot.
blown head gasket,it causes the coolant and gas get mixed in cylinder,that cause the white smokeyou also loose compression which in return you loose power
Catalytic converters clog due to the carbon that the car produces. Usually, when the carbon has built up inside the cat., black smoke will come out of the tailpipe when you rev the engine. In extreme cases, black soot is visible on the ground next to the vehicle's tailpipe. Crystal Woll
No 6ecause if that was the case and there was somthing blocking the tailpipe, that was strong enuff to do that the preasure from that would either force the enigine to stop or it would bust the weld on the excuast so no that wont happen
You have a blown head gasket.
the engine is burning oil. blue smoke oil white smoke antifreeze black smoke excess fuel
Sometimes feces can come out black because they have blood in them. This is the usual cause of black stool.
your moms vag juices not water
You have an Exhaust leak, you need to get this fixed immediately. Carbon Monoxide can KILL.
If your block is cracked engine coolant may be leaking into the combustion chambers.
