Motor surging

[95Firebirdred]

I just had to replace the water pump, distributor, plugs, wires, and fuel pump. I am geting bad surging. When you rev the engine it is like it is starving for gas. If you get in the throttle slow it doesn't act like that. All this happend after I replaced all those parts. I have also changed the tps and the map sensor, and put new o rings on the injectors. The injectors are squirting good. I have a lt1. Can anyone help me with this problem. I have been working on this for 2weeks and can't figure it out.

Why did you replace all those parts, particularly the fuel pump? I'm guessing the water pump leaked (possiblly onto the Opti-spark dist) and while you had it apart you replaced the dist and did the tune-up as maintenance but why the fuel pump?
Have you checked your fuel pressure?
