Start by checking the fuel injectors for any clogs or issues, as they can cause misfires when the engine is warm. You can try using a fuel injector cleaner to see if it improves the situation. If the problem persists, it might be worth having a professional inspect the fuel system. Let me know how it goes or if you have any further questions!
Thank you for the answer, I will check this too. It does this when it's warm, then it might clear with diagnostics, and it appears the next day or it depends how much I've driven.

Consider checking the engine's coolant temperature sensor as well. A faulty sensor can send incorrect signals to the engine control unit, affecting fuel mixture and causing misfires when the engine is warm. If you have any further questions or need more assistance, feel free to ask!

She said that after the check engine light comes on, it runs unevenly, as if it's on fewer cylinders. I'll check that sensor. Thanks. After we clear the error, it starts and runs normally, and after a few hours it does it again when starting a warm engine.

And the diagnostics record cylinders

Check the condition of the crankshaft position sensor. A failing sensor can cause intermittent misfires and uneven running, especially when the engine is warm. If the sensor is faulty, it may not provide accurate readings to the engine control unit, leading to the issues you're experiencing. Let me know if this helps or if you have any other questions!
