The mass air flow sensor and throttle body seem okay at first glance, but I'm no expert. You really think it might be the oxygen sensor? Or maybe something with the catalytic converter? I'm not sure, where should I start looking?

Yeah, the oxygen sensor thing was just a wild guess, honestly. For me, it turned out to be a bad injector on cylinder 3. Given your hybrid setup, things could be more complex. I'd get it checked by a workshop. Save yourself the headache.

I was hoping to avoid that. You're probably right, though. It WAS a defective injector, like I suspected. Cost me 515€ to repair. Thanks for the advice!

Sounds rough! I had similar symptoms on my old Opel Insignia, but that was a diesel. Have you checked the mass air flow sensor or the throttle body? Just throwing out ideas here, could even be a faulty oxygen sensor. Is there anything else that could cause too little fuel?
