Tony, not much information to go on here. Your rough idle could be cause by a bunch of things. Anything from faulty plugs, to low fuel pressure, filters, to injector issues,a dirty TB or a IAC problem.
Please post more information Like miles on the engine, recent maintenance or any codes?

What have you checked? Are the plugs good? Are you getting a blue flame at the plugs? Are the wires leaking? Is the fuel pressure KOEO good? Does it hold pressure after shutdown? What is the WOT fuel pressure?
