rough idle not CEL

so I have a 2001 edge 3.0 and it seems to idle a little bit rough. It never stalls and the CEL never comes on but it shakes a little bit and surges up and down. I have changed spark plugs, wires, fuel filter, cleaned the TB, IAC, and about to clean the MAF. Any other ideas? Would I be better off just buying a new IAC and possibly and EGR valve?

had my iac cleaned before i traded in the ranger

turns out my iac was jammed open from the k+n filter oil drying out and particles flowing into the iac port

hence my partially rough idle

ok well I have cleaned the IAC but it still idles a bit rough. so I think I`ll go out and get a new one and hopefully that solves the problem.

After cleaning everything, changing the plugs and wires and beating my head against concrete, I found a vacuum leak, driver's side rear of engine, on the PVC hose. It wasnt split, it had a small leak between the rubber and plastic, and the grommet holding the PVC in was also leaking. Some cleaning, zip ties and it runs like new.....
