Problem Description and Possible Solution

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.
Having a problem with fuel smell rough idle when stopped but idles, fuel over load is what it smells like when stopped. The truck starts acting up after a good 20 to 25 minutes of driving. act's like
Engine starts vary poorly will not idle and then shuts off, and it smells of heavy gas fumes in the exhaust. Truck was fine yesterday and then this happened.
shaking real bad while driving and while idling
Idels very rough ...Bought it NEW. Have maintained very regular...Replaced original IAC...No improvement...My mechanic is at a dead end.....Have not cleaned throttle body as yet. I am thinking it may be the TPS ($42.00)....Need your advice....

2006 F150 5.4 Starts and runs smooth until warming up to operating temp. At this point it starts to idle rough and engine sounds like it's starving for oil. If I raise the rpm it goes away.
clean out the EGR with cimtool.
Truck runs ide and rough driving at the first 2 miles then after 45 miles you can feel the rough running condition.

2010 Ford F150 5.4 Liter. Occurs at low idle rpm in gear. Feels and sounds like the engine is going to blow up and shake the truck apart. Let off and go to neutral and rev a little and it goes away.
SOUNDS LIKE AN EXHAUST LEAK UNDER DRIVERS SIDE
Runs ruins rug at idle. And when ac on
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.
making noise at idle like diesel truck and make it vibration I have t hold the throttle I little bit to evade the noise and vibration !
