I went on a 45-minute trip yesterday, and I swear it felt like it was jerking ever-so-slightly while I was driving on the highway. When I pulled in the driveway, I could once again tell it was doing the occasional "sputter", so I grabbed the phone and recorded it.

The first time, the truck did what it most-often does; it almost died, but then kept running.
Some time passed (about a minute), and I edited it out of the video.
Then, the truck stuttered and cut off this time.

What is the cause of this?
This is "driving" me mad!

Mine is not fixed yet $500 for a new purge valve and battery and it’s just as bad as before

My 2015 started doing this about 5000 miles ago. I have 68K on the truck now. It is starting to affect the performance when I'm not idling. I was going to start with spark plugs and coils, but it sounds like it might be more complex than that!

I went to my mechanic today, and I started off by telling him about the homework done on both this forum, and others. After explaining the problem, the mechanic realized that we needed an "in flight recorder" to diagnose the problem in real-time -- they did not have this device.

However, the mechanic did connect a standard OBD II device to the truck while it was running (again, my truck has no check-engine light on). As he was scrolling through real-time data on his scanner, he noticed the intake air-temperature was reading 109-degrees Fahrenheit, which then climbed to 111-degrees. The outside temperature was 50-degrees at the time, so 111-degrees seemed high.
Does it seem high to anyone else?


Also, based on the information on this thread RE the purge valve, I decided to pull the plug and disconnect mine, just to see what happened. No codes thrown. I have driven only 5 miles with it disconnected, so no definitive findings yet, but we'll see.

It seems like my problem worsens when the weather is warmer. Since our high temp was only 50 today, and with our local temps being colder the rest of the week, not sure how this will affect my test.

Lastly, I am in contact with another guy with the same problem who is not on this forum... we are communicating on this YouTube video about our attempts at finding the issue and working solution (https://goo.gl/LmqMR9). Check it out and see if your issue looks like mine, or feel free to read the comments section there to see if there is anything helpful for you.

My truck finally threw some codes at 70k miles. I got three but the P0061 seem to be the most informative.
Here is the information I read from this link, notice the symptoms...
P0061 code definition
P0061 announces that the vehicle’s computer detects an unusual resistance level with oxygen sensor bank 2 sensor 3. An oxygen sensor is used to monitor the the amount of oxygen and harmful exhaust elements exiting the engine. The computer of the vehicle will use the readings of the oxygen sensor to adjust the performance of the engine by changing the air, fuel ratio, and ignition timing.

What the P0061 code means
This trouble code indicates that there is an abnormal resistance detected with the bank 2 sensor 3 oxygen sensor. The oxygen sensors are located on the exhaust pipes and are used by the vehicle’s computer to monitor the amount of fuel being consumed by the engine, as well as the levels of pollutants being created by the engine.

The sensors however are only accurate when they reach a hot temperature of about 600 degrees Fahrenheit. The exhaust pipes themselves would take about 15 minutes of operation to reach such temperatures, but an accurate reading of the oxygen sensor is needed long before that time period. This is why internal heaters were added to the oxygen sensors. The computer will interpret the temperature of the oxygen sensor by reading the resistance of the sensor. If the resistance of the oxygen sensor is out of range, that indicates to the computer that the temperature of the sensor is out of operating range as well.

What causes the P0061 code?
A short in the wiring, wiring harness, or connectors of bank 2 sensor 3

An open in the wiring, wiring harness, or connectors of bank 2 sensor 3

Worn internal heater element

Faulty power control module

What are the symptoms of the P0061 code?
Idle stumbles up and down
Check Engine Light or service engine light will soon illuminate
Loss of power or acceleration
Engine stall

That is very interesting. I assume you will have your O2 sensors replaced, since those are a relatively inexpensive option. I would like to know how it fares after that. I have to go on a road trip to Syracuse on Jan 5th, and I really, really don't want to drive the truck with issues that far from home (NC).

Also, I did reconnect my purge valve. The day after I disconnected it, the check engine light came on. I thought the truck was driving better, but in reality my trips were so short for the first week I had it disconnected, the truck never had a chance to act weird. Then, I drove for about 45 minutes, and it started up just like it always did, so I 99% ruled out a fault purge valve.

Keep this post update with the O2 sensor replacement (or whatever else you do) please. This is very helpful information.

My issue started in August 2017 at approx 20k miles. On one outing it occurred twice. At traffic light idle would drop and truck would stall. It escalated to occurring every other week. It never happens when going from point A to point B. It always occurred where I had multiple stops doing errands.

Brought to dealer on Dec 5 and was told it was showing codes indicating the throttle body and was replaced. Within three days (Dec 8) it problem happened every day for 5 days even on short trips.

Brought back in on Dec 13. Was OK for about a 7 days and and had 4 occurrences of rough idle and stalling to date (Dec 30). Replace throttle body again stating the part was bad. Going back to dealer on Jan 3.

This is my third visit to the dealer. If not repaired after this visit will the New Jersey Lemon Law apply. I am below the mileage and time max. Still under warranty at 28k miles.

Latest update. I got a P0012 cam sensor error. Took it in and the dealer has determined it has a bad cam phaser on bank 1 that is going to be replaced. Hopefully this is the fix

Got my truck back from the dealer on Tuesday (Jan 24) and as of now (Sunday Jan 28) everything is good. Drove a lot of stop and go trips without any issues. Dealer replaced both VCT solenoids. Codes P0011 and P0012 showed up. What could cause these solenoids to go? Is this something to be concerned about in the future. As of now I feel the problem is fixed. Will report again only if issue pops up again.
