Espace Hybrid Engine Trouble

My 2023 Renault Espace hybrid is acting up with 104562 km on it. The engine feels super weak, the check engine light is on, it runs rough and it's jerking like crazy when I try to accelerate. Could it be a defective injector? Anyone seen this before?

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?

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!
