I've seen other posts on this, but only one that I found had a possible answer, but not one that seemed to work for most.
2014 Ram 1500 Express 5.7L Hemi - 109k miles
Here are some videos of what's happening.
This usually happens when the truck first runs for the day. If I don't notice it right away, I'll leave the house, drive for a few miles and then pull over to turn the truck on/off again. This generally fixes it right away.
In the videos, you'll also notice an instance where the jump was about 200-300 RPMs, and the Battery Voltage was also jumping. When this happened, I turned it off/on, and it went away. This was the most severe instance I've had, normally, it's only ~100 RPM jump.
The video with lower RPM is when it's at idle and not moving. The higher RPM videos are shot around 40-55mph with the truck on cruise control. Road is relatively flat, days are not windy.
I've changed the spark plugs (needed it anyhow due to mileage) and also cleaned the throttle body. Still, have this issue.
The other thread mentioned changing out the transmission fluid 3x. I have not done this yet. Curious if anyone else has thoughts or has found a fix, as the oil fluid didn't seem to work for everyone, and/or the issue came back. Here is a link to that answer.
