Yes, the error code pointed towards a cylinder misfire, specifically the fuel injection system. Do you think it's a defective fuel injector? Did yours show similar error codes?

Yep, that's exactly what mine was doing. Cylinder misfire code. If the code points to the fuel injection and the plugs are okay, it’s probably best to take it to a workshop to have the injectors checked. It could be a faulty injector, but they’ll be able to diagnose it properly.

Took it to the workshop, and the diagnosis confirmed a defective fuel injector. The repair cost was 515€. They replaced the faulty injector, and now the engine runs smoothly again. Thanks for the help!

Hey, I had something similar with my Cronos. Rough idle, check engine light… sounds familiar. Did you get any error codes read? Could be a cylinder misfire. Any codes related to a specific cylinder?
