What are you using for fuel?

Trims look a little wonky, and timing doesn’t look great

Plugs or coils generally for the misfire..

Trims can be o2 or injector related

Let’s get your misfire fixed first & review logs

Nothing glaring in the logs.

Have you cleared & it comes back?

Could be a few things...

You’ll throw mixture codes for a few reasons- tune related is when trims max positive or negative for too long

Given your morning start issues- let the car sit overnight & pull your spark plugs- check if they’re wet with gas... if yes- I would imagine your injectors need replacing / are causing the mixture control code.

Might be worth replacing especially at that mileage regardless
