RPM Play

I have a 1996 Discovery 1.

I have a slight RPM play at idle. Recently changed MAF( air mass flow) and it improved situation. Also changed TPs ( throttle position sensor) and ignition module. Truck used to have high RPM play and high emissions. It used to be noticeable when I drive up the mountains at 1000 m plus.
Much better now.

Still for the remaining play => Could it be from the stepper motor still ?

thank you
