Too much fuel is the usual problem.
One of the injectors may be stuck open, or some other fuel leak into the engine.

EXHAUST TROUBLE SHOOTING


If smoke is black indicates too much fuel
If smoke is white Could be coolant in the exhaust system
If smoke is blue possible excessive oil entering in the combustion system
Also if you have an automatic transmission with a vacuum modulator, it could be leaking transmission into the combustion
If you have too much oil in the engine, it will also smoke

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 !!
