Elysion Engine Misfires

I'm having trouble with my 2023 Honda Elysion hybrid. It has 227416 km on it. Lately, the engine runs rough, the check engine light is on, it jerks when I accelerate, and engine power is noticeably down. Could combustion misfires be the cause?

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.

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.

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€.
