Low rpm stumble

Low rpm stumble
My 4.0 has a bit of a low rpm stumble to it. Around 1,500-2,000 rpm under load the truck starts to buck/ stumble. I've cleaned the MAF, changed plugs/ wires, unhooked the EGR to test, and replaced an O2 that a scanner said was bad. Does anyone have any ideas on what it could be?
