Car Revs to Really High RPM on Startup

I'm having an intermittent issue where my car revs to 5,000-6,000 RPM on startup.

At first, I thought I might have been stepping on the brake and gas while starting the car, but it's happened quite a few times and it's not that.

Has anyone else experienced this issue?

noticed mine gets “stuck” on cold starts In high rpms for a few seconds if I just tap the gas ( which I know I shouldn’t)

This is exactly what happens to me, but since it started, I've been extra careful to make sure I'm not touching the gas at all.

I'll bring it in later if it persists!

Hey I think its got something to do with the extreme cold temperatures we have had recently. This morning I noticed the higher rpms on startup as well.

Started the car for almost 20 min and only one white bar appeared in the odometer! I was also hearing a sound when I released the gas pedal in that frigid cold.
