Default Idle and driving problem

So here it is. Ok the truck is 2001 5 speed ranger edge with a 4.0. Its got 90k on it. Recently the check engine light came on saying egr and o2 sensor so i change thoes and it comes on again. The truck is sputtering at idle and kick a bit while driving. It does this randomly one second it will idle fine the next it will idle up then down at stop signs. I changed fuel filter spark plugs and wires and maf sensor with no luck. At my brothers shop the computer was saying have he motor wants 30% fuel and the other wants 70% fuel. when you run it for a while you can smell raw fuel and if you rev it up it shots out lots of black smoke of unused fuel. Are my cats blocks or something im totaly lost about ready to just trash the truck
