ford explorer 2008 4.0

problem is rough idle engine hesitation at idle or when stop at traffic light.

codes showing

4 oxygen sensor.
EGR valve.
purge control valve.

yesterday i change the 2 front o2 sensors but no difference and the codes still shwoing.

i tried change fuel pump
clean fuel injectors.
spark plug.
check coil body from another same model car.
change fuel filter.

is this the pcm problem?
