Elysion Engine Misfires
Summary of the thread
The 2023 Honda Elysion hybrid experienced rough engine performance, a check engine light, jerking during acceleration, and reduced power, suggesting possible combustion misfires. Potential causes included issues with fuel delivery or ignition timing, particularly a defective injection valve or injector. A workshop confirmed a defective injector as the cause, leading to its replacement.

The check engine light hasn't flashed. If it's not the codes, could a defective injection valve or injector explain the combustion misfires?

Yes, a defective injection valve or injector certainly aligns with combustion misfires. A faulty injector can disrupt the proper air/fuel mixture, leading to incomplete combustion and misfires. Given the mileage, it's not entirely unexpected. However, it would be wise to have a workshop confirm the diagnosis and rule out other potential causes. Have you thought about doing that?

Thanks for the advice. I took it to a workshop, and they confirmed a defective injector. The repair cost 515€.

Given the rough running, check engine light, jerking, and power loss, misfires are certainly possible. Has the check engine light flashed? If it has, that would strongly suggest a more severe misfire. The jerking on acceleration points to a potential issue with fuel delivery or ignition timing, both of which can be affected by faulty injectors. Have you had the fault codes read? That would give a clearer idea of which cylinder, or cylinders, are misfiring.
