When at a stop with the engine idling, it is idling typically at 800 rpm and it feels quite rough. Same is true if sitting in my driveway in Park and the engine cycles on to maintain air conditioning. Is this the typical idle speed for this engine?

 

If it's bothering you, de select eco idle in the settings.

 

I experience this sometimes also. I have the high idle mode on and most of the times it idles around 1300 or so for fast charging, but occasionally it runs rough at 800. Not often enough where it really bothers me, but I am surprised how rough it is at that speed and was thinking about asking dealer about it at next service appt.

 

That would just make the truck idle around 800 RPM all the time and wouldn't do anything for the OP's complaint.

I have the same thing. You may get a slight improvement with the PCM updates that are available, but most likely not. I think it's just a slightly more rough RPM in the band. Every automatic vehicle I've ever driven has done vibration when stopped and in drive or reverse, but the F-150 is probably the worst. If I know I'm going to be sitting someplace for a little and the engine will be running during that time, I just shift to neutral until I'm ready to move.

 

Good replies. I just took delivery of the new truck and am trying to figure everything out so it was more of an "is this normal" question rather than a complaint. I've had three F-150 previously with the 3.5 EcoBoost and none idled like this one which is the main reason I asked. I suppose at slow idle it still has a load on it in the form of a generator so that could account for the roughness of the idle. Thanks for your responses.

 

I notice the same thing. Not as smooth as the 3.5, 2.7, and 5.0 I have had in the past 10 plus years.
