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.

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

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.

Truck runs ide and rough driving at the first 2 miles then after 45 miles you can feel the rough running condition.
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.

Rough idle when sitting and diesel sound coming from engine. Shops will sell you on a cam timing phaser replacement at about $1800. All you need to do is: CLEAN YOUR THROTTLE BODY for the rough idle. REPLACE THE VARIABLE CAM TIMING SOLENOIDS to quiet the diesel rattle. If you do it yourself, it costs $120 for both (buy the solenoids off ebay) including a $10 bottle of throttle body cleaner. Go to youtube and search what I have given you and there are numerous videos. I was ready to drive my truck off a cliff until I took the advice I am now giving. It works. CHANGE YOUR AIR FILTER REGULARLY to prevent the rapid throttle body gum-up. You are welcome!
