I recently had to get a new engine for my 95 4.3 well now the new engine is in but its not accelerating right it will take off but if I push on it it won't accelerate it revs up but don't go any faster then when I let off the pedal it will jump up. If I floor it, it just starts puting the guy that put my engine in said I have a weak fuel pump which I already knew but would that cause my car to do that. I even swapped my old tb with this one but I still get the same problem.
