I've got this same problem with my 1986 300zx.. I took it to the dealer for repair... This is what they told me.. The Air Flow Regulator, had some rust, which would cause it to not seal correctly.. So, my AIR / FUEL ratio was off balance.. The black smoke was a result of my engine getting too much fuel, and not enough air.. The part cost $500 from the dealership.. And anywhere from $200-$450 from other source...
