Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. The valve and sensor must be replaced together to correct this concern.

    At Idle my F-150 5.4L runs with an intermittent roughness. Not noticeable on the tachometer but you can feel it. No codes on the OBD. Going to try engine/plug tune-up.

    EGR code verified for free at Advanced Auto Parts, they can check the codes for free but will not clear them. Autozone also provides this service.
