2019 Kia forte LXS P0012?

2019 Kia forte LXS, car had a P0012 code which has gone away but problem persists. I also get a P0171 code that sometimes appears for a day when I fill up on gas. To start my car drives fine when on the gas. I have no problems with acceleration or timing slipping. But when I’m coming to a stop, coasting into a parking spot or coasting around the corner from a stop sign my car likes to lunge forward. The video is me coasting with no feet on the pedals, you can see my rpm jumping from 500-1400. I’ve replaced the VVT solenoids, spark plugs, fuel injectors, ignition coils.
Going to clean the throttle body today but other than that I’m lost. Any advice would be greatly appreciated
