2002 plain decline instability

Good morning to all, I have a problem with a 2002 Platina, it happens that the vehicle turns on, on low is unstable and by accelerating black smoke and smells like gasoline.

I already checked coils, and they are fine, the spark plugs have 1 month that they were changed, the acceleration body was already washed and the oxygen sensors were changed. A busted injector was changed, the admission packaging changed, and I think it's all

ah, the silencer was also changed and the catalyst was removed.

But still my problem persists, I hope someone can help me. Thank you.
