Rough Idle Caused by EGR Sensor Sticking on Ford F-150

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.

Mine runs fine until it gets warm usually 20 30 min of freeway, then when put in reverse or pulling into parking spot, drops to very low idle and sounds like the loudest diesl motor, hit throttl to up idle and back to normal. Have found no one that can tell me where to begin. no engine lights

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.

After warming up the truck for 10 to 20 minutes. When I idle down to put into reverse I no longer have a gas motor it turns into a loud rattling diesel. No codes and no idea why it does it.
