Question

Answer 1

The black smoke is oil burning.

As in you need a ring job.

If it was black smoke when you start it up then my guess would be valve guides.

Pull a plug and I will bet it will be oil fouled. If not one there will be at least one that is and that is why you have trouble at idle.    

Answer 2

HOW OLD IS IT ?

Answer 3

First check your mileage if it is less than early one then consult a mechanic whether the inlet valve of any of the cylinders.

Answer 4

White smoke means your car is burning oil.

Black smoke is from incomplete fuel combustion.

That means your car is getting too much fuel

or not enough oxygen. Your best bet is to take it to

to an auto shop and get it fixed.

One last easy thing you can try to do though is change

the air filter. It may be extremely dirty  and that could

cause low air supply to the engine, black  smoke,

and stalling.

Answer 5

Black smoke usually indicate a fuel problem.

To much fuel or flooding is most likeky the culprit.

A glogged injector or a carburator in need of rebuild

in most likely the trouble.Injector cleaner is not going to solve the problem,it is designed to maintain clean injectors.

Answer 6

Your piston rings are probably shot,

If not could be the spark plugs, ignition leads (might not be sparking sufficiently to burn the fuel) I would replace them as well as the fuel filter, Oil change and the usual, if its still not fixed i would take it to a mechanic
