Engine runs rough at times while idling or
driving

How long since a tune-up? Any applicable trouble codes? If you have tac/throttle actuator control, I usually think of that system first. Any codes relating to that system? You could try cleaning throttle bore, see if it helps the idle? Don't force the throttle plate. Might be other issues?
