Black smoke it caused by too much fuel so you might have a stuck fuel injector, I would remove the spark plugs to see which ones are black, this will be the cylinder having the problem and where the fuel injectors needs to be replaced, I would replace all of them but that is up to you. Here is a guide to help you
