Truck has been running great for the last 7,000 miles. Randomly today while cruising the logging roads it started to act up. Idles between 200-400 and just fluctuated back and fourth. I drove it home 2 hours away at 70mph with no issues at all. No power loss or sluggish feeling. Only acts up at idle. Thanks for any help. Any input is appreciated

Here's a video. Notice the excessive cranking (not normal for my rig)

Have you looked under the truck to see if maybe some wires were ripped off?
The oxygen sensor wire for example. I have had some issues when going through rough terrain because of that. My,tail lights, backup lights etc.

I did a little quick poking around, haven't found anything obvious. Gonna head back out to the shop after dinner and poke around some more.

I do think it's a loose connection or something came unplugged. It seemed like it started right after hitting a couple potholes

Still haven't solved this. I'm out of ideas

Edited: solved issue.
Sticky egr. Gave it a few love taps with a ratchet and instantly purred like a kitten.

Have you tried getting a problem using the OBI ? On the diagnostic box it is right by the fuse box inside the hood. You remove the cap on the little diagnostic box and inside the cap you will find the letters or symbols . You short T and E1 or T1 and E1 . Your check engine light will start flashing. It will give you the code in blinks on the check engine light. If it starts with 1 blink everything is normal if it starts with 2 or more the ECM has detected a problem.
Maybe you can find the OBI trouble shooting codes on this post. It may be your EGR or a vacuum leak or the EGR regulator. Some thing to do with any of these EVAP subjects. It just depends on what code(s) you get.
