Peugeot 108 Engine Running Lean

My 2022 Peugeot 108 (gasoline engine) feels like it's running lean. I've noticed reduced power, the check engine light is on, and it runs really rough, especially when accelerating. Mileage is at 62042 km. Any ideas?

That sounds similar to what happened with my old 2014 Opel Astra. Same symptoms: Check engine light, rough running, and loss of power. Have you checked the oxygen sensor or maybe even the spark plugs? It could also be a problem with the throttle body...

Oxygen sensor and throttle body? Were those the issues with your Astra? Was it also jerking when accelerating?

Yeah, pretty much. Turned out to be faulty fuel injectors in the end, but the symptoms were identical. Definitely get it checked out by a workshop before it causes more damage to the catalytic converter! Good luck!

I took it to the workshop, and you were right – defective fuel injector. Cost me 515€ to replace. Appreciate the help!
