You have an excess fuel delivery problem. Black smoke indicates that too much fuel is entering the combustion chamber. If this vehicle has a carburator, check the float bowl level. If it is injected the main things to look for would be a stuck throttle position sensor or an injector that is not closing

Why does my 1998 infinity q45 kills after idling for about 20 minutes, it will restart but blows out black smoke?


Black smoke means that it has gotten too much fuel from the intake. That is a sign that either the timing or valves are having issues. It could also be that the crank sensor is failing. The sensor controls the pulses to the ignition. There is also a cam sensor that might be having issues. It is curious that it is happening at idle. One of the causes could be heat.

Sounds as if you are running extremely lean.Has EGR been bypassed maybe?
What is fuel pressure,on that vehicle the fuel pressure regulator may be adjustable.Some of these had an allen screw inside the vacuum port where you could richen the mixture some.Also try backing down on the timing a few degrees.
