Weird problem

Hello guys, I own an s60 2001
I got a weird problem with I can't figure how to fix or what is it related too

When I drive steady between 60-80 mph, for few seconds, my rpm starts to jump/dance by 200-300 till I either increase gas or not push at all. It does not happen above 80 or under 60.
I've cleaned my maf and throttle.
It did help a in general but the problem still there.
I've tested the voltage of maf with a mechanic and he said its a bit low.

Any ideas/suggestion?

Befor iv cleaned the maf(I also reset it)
My rpm was dropping by under 1k at stopping and downshifting, but now it seems like fixed.
