96 Cherokee Sputters

4.o Automatic Sputters For First Mile Or So Then Straightens Up As Though Nothing Wrong. Changed O2 Sensors Twice, Crank & Cam Position Sensors 2x, Had Head Reworked, Changed Out Wiring For Cam & Crank, O2 Sensors, Coolant Sensors, Changed Out Computer Twice. Problem Still There - Any Ideas?

Check IAC, TPS and check the MAP sensor.
