Have the fuel pump checked to insure it is delivering fuel at the right pressure and the injectors match its pressure capability.
You don't mention any trouble codes? Not a big fan of replacing parts until the problem goes away. What was the original problem? If you have a bad crank sensor or TPS the engine will respond the way you describe, but there are also dozens of other issues that can cause the engine to have no power.

We had the same problem and our mechanicfound at last it was the air flow sensor!!!! Runs well now.

remove the O2 sensor before the cat. by the exhaust manifold and if the vehicle runs much better there is a clog in the exhaust system, most likely the cat.
