Fullinject Taurus 98

Hello, good morning, I could help me, I am new in this forum,
the fault of the car is not found the failure is that it loses strength when it is running
and when I am rooting high in low, the engine trembles and smells a lot of gasoline when it fails and takes black smoke when it accelerates. Before that happened to him, he was adding to the injectors called Lucas and had half tanke and ran it to the long road and went out on the road he had to turn off the car and turn it on and marched well and then he was bolvia turned off.
Some say it is the gasoline regulator ..... I hope and can help me. thanks
