SOURCE: my dodge caravan 2001 is bringing out black smoke

it is usually one of the O2 sensors is bad/i had the same problem with my 2001 dodge grand caravan sport/it may not be the muffler or the catalytic converter necessarily. take the car to either autozone or oreilly's and have them put the engine code reader on it/its free and only takes a minute/ my car has (2) O2 sensors. it would be best to give your VIN number to the dealer so they can tell you which of 4 possible O2 sensors you will need. then you can compare and shop online for the part. Some O2 sensors have 2 wires, some 3, and some 4 so there isn't just 1 part it could be. some O2 sensors also have very short wiring harnesses, so if you get one, make sure the wiring on it is long, not short, or the mechanic is going to have to rig it to make it work.

How do i fix


Black smoke is from running too rich and also why your mileage is poor. This could have many causes from a leaky fuel injector to excessive fuel pressure. The fuel system needs to be checked and evaluated.

Black smoke coming from exhaust pipe


black smoke is coming from exhaust possible causes--- excess fuel enters cylinders and does not burn completely. poor fuel milage is also a common complaint, when black smoke comes out tailpipe its running to rich!! This can be caused by anything from a computer malfunction to a leaking fuel injector. A possible fix would possibly be a tune up or carburetor/fuel injection work. run some good injector cleaner in it, it may fix the problem. but if not check it out further. good-day !!

The engine 4.6 gets alot of smog,I think,the problem maybe wil be the regulator presure of fuel pump. Because was liquing gasoline throw the mofles . Do you agree? It ocurres about one minute after I...


If the smoke is white, it is caused from burning oil. It it was gas it would be black. If the smoke is coming from the exhaust pipe then the oil is leaking into the combustion chamber of the engine. If it is coming from under the hood then there is an external leak that is getting on the exhaust system and burning off.

Black smoke and soot coming out of the exhaust pipe


Black smoke is caused when the mix of fuel and air becomes un-balanced. Normal mixture is 14.5 parts air to1 part fuel. When the fuel to air mixtures change because of a malfunction the mixture can go as high as 14.5 to 2 or 3, two to three times the proper amount. The black smoke is the excess fuel generated from the rich mixture and can be cause by one of the following:
  • plugged air filter
  • Shorted or stuck fuel injector
  • Failed fuel pressure regulator
  • Vacuum leak
  • Shorted ECM Sensor , scan for any problem codes if possible.

My Honda Odyssey 1995 consumes lot of fuel and the check engine indicator lights up. My full tank can barely take me 200 km


Sounds like it is running too rich and you will need to replace the fuel control module. If the exhaust is blowing black smoke then it will only be a matter of time before you get stranded on the road. You should also be experiencing a loss of engine performance especially going up hill.
