WHAT CAUSES ACCELERATION HESITATION?

1989 Chevrolet Corsica • 226,000 miles

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.
