Engine revving “ghost”
So I’m at a stop sign in my C7, just minding our own business/waiting for our chance to go, when the engine starts revving rather scarily, climbing all the way to or near 6K; not sure what to do, but after a few seconds of panic I shoved it into neutral and may have just tapped the gas pedal - in any case it calmed back down to normal idle revs, although it also temporarily sent the oil temp gauge to 205+, and left a lingering smell of singed oil. Ran fine after that for the remaining hour or so of the drive. Anyway, to my questions - what might cause this? Might something I did have been to blame? Anything I could’ve/ should’ve done to arrest the rev spike quickly & safely?

No, it hasn’t been tuned, just regular maintenance; as far as I’m aware (bought it used, and I’m no wrench), it’s entirely stock, the maintenance records/history and what I think I know of the previous owner make an add- on like a Pedal Commander unlikely.
