Hey guys, got a 2016 F150 with 5.0 at 30k miles. This morning I noticed that my idle seemed different that usual. I could hear the engine idling up and down. Even could see it on the rpm gauge. I am going to take it in to the shop. Anyone have any idea what causes this? What exactly do I call this, just a rough idle?

 

I had that issue with my 14 5.0 on cold mornings, just went away after going to supreme fuel.

 

Yes I have the same problem. It started with rough idle and stalling every now and then. Now happens daily. At dealer three times without fix. Going back next week.

There is a thread on this already that I added to. Please message me if you get any where. Thanks

 

Can you connect us to the other thread?

 

Do a search for the above thread

 

Rough idle is more of a stumbling that you can feel. Sounds like you have a hunting idle.

Rough idle is often a spark energy issue. Bad or fouled plugs, bad coils.

Hunting or surging idle is often a vacuum leak, bad air flow data (failing MAF/MAP sensor), or bad throttle position info.

 

My problem was with the VCT solenoids. Codes P0011 and P0012 showed up. The problem was when stopping at traffic light/stop sign the idle would fluctuate and then stall. Both solenoids were replaced and everything is good.

Or better yet, just start a new thread for yourself!

 

**** (idle) happens.

 

Hey everyone my 2016 XLT Scab just started doing it this week at 45k, I let the oil monitor get to 20% and sure enough it threw a p0022 code. I took it to the dealer and the are in the process of putting in 2 new cam phasers and new VCT solenoids. They said it’s covered by warranty but wouldn’t pay for a rental which is BS but whatever. I hope this is a one time fix and not a ongoing problem, all I ever hear is how bulletproof the 5.0 coyote is, not seeing it with this kind of problem at 45k already. Like someone else said if you get a rough idle at stops be sure to let the Oíl life run down to 20% so it throws the code and get it to the dealer before 60k warranty expires. My build was 10/2016, looks like they may have had a bad batch of Cam phasers towards the end of 2016.. I ll update when I get the truck back next week
