WHAT CAUSES ACCELERATION HESITATION?

Recently my 89' Corsica has not been accelerating correctly. Its been slow to take off and as it tries to gain speed, it does it slowly and sometimes a little********. I've replaced the O2 sensor, Throttle Position Sensor, Air In-Take Sensor, Mass Air Flow Sensor (MAP), Spark Plugs/Wires and the Fuel Injector as well and it has gotten better but the problem has not gone away.
I need serious help, the check engine light told me it was the MAP Sensor and that's been replaced.

Do you
