The basics for a rough idle, check for a leak of some kind, fuel--egr--vacuum.
Problem at higher rpms, the basics, check for a blockage of some kind, the two things I think of first is fuel and exhaust.
I'd use a gage and check proper fuel pressure. Also, see if fuel pressure holds for a bit with everything off.
Could be other issues.
