There could be many items that could cause rough idle but the first thing that comes to mind is a faulty EGR valve allowing exhaust gas into the intake system at idle. Check the EGR valve for leaking, and if that's not it, check the obvious things like intake vacuum leaks, sparkplugs and wires, etc.
