Black smoke means that your engine is running too rich as in it,s getting too much fuel. I would only be guessing as to what the problem might be so your best bet is to have it checked out and find out for sure instead of throwing a bunch of parts at it.

none of them give you the right answer when a 30 year tech says no problem makes you wonder where he worked it is not supose to smoke even when more fuel enters the engine change the oxygen sensor and it will solve the problem it is getting carbon built up on it and it is causeing it to send signals to the computer to change the fuel mixture

No problem found. In order for the engine to accelerate extra fuel is squirted in when the throttle plates turn rapidly. Vacuum drops extra fuel is needed to get the motor turning

Diesel or gas?
Diesel's do this with #2 fuel
Gas does this when yoiur choke is sticking or plugged air filter causing it to choke out.
