When I was in jail, i tried my escape, then I picked up a torch, and wile in sneakrunning mode, I put torch in favorites(8 key) then i equipped the items, and BUMMMMMMM Nitro mode!!!
I was running like in "normal" mode and not in sneak mode, is this normal???

it's a bug i have had it a few times both in dungeons and in the open world, just stop and start walking again and its fixed not a major thing, if your in 3'rd person your legs dont move either there ''gliding''

It happens with all weapons aswell, if you equipt a weapon while moving forward in sneak mode u will move as fast as you do while running.

I had a torch favorited, equiped in my left hand, and I could sprint indefinitely

If it is a bug I hope they don't fix it. I keep getting encoumbered and it allows me to run home.
