engine is not foked,

Black smoke is overfueling, which means you will need to check the lambda and the injectors......... however over fueling on high revs isnt really a majour problem.

However if you want it fixed either put it on some diagnostics and see what the problem is or change the lambda & give it some redex

Over fuelling is better than running too lean. Most cars put some black smoke out when high reving so dont worry.
