RPM jumping (not eTorque)

[Anarxi]

Happened few times, i start my truck and rpm is jumping from 1k to 1,5k evenly. if i try to drive out it slightly stuttering mildly but noticebly. also i had it rev up slightly once when braking, not sure if its connected. just put 10k on the truck. the revving up happens on cold start, the braking rpm jump was already on warm engine. any ideas (5.7 hemi 3.92 gear ratio)

Read through the engine related TSBs. If I remember correctly, I think there is one related to what you're describing.

braking rpm thing might have been your foot on brake and also on edge of accelerator? Happened to me a couple times especially with boots.
