O2 sensor seems okay, haven't checked the cat. What was your issue, exactly?

Yep, injectors were the problem. Get it checked ASAP. A faulty injector can cause a lot of damage in short order. If it's overfueling, you risk washing down the cylinder walls and damaging the engine. I'd recommend taking it to a workshop.

Thanks. Turns out it was a defective injector, as suspected. Cost 515€ to repair.

Rich mixture on a Boxer? Sounds familiar. Had similar symptoms - check engine light, poor fuel economy, rough idle. Did you check the O2 sensor? Is your catalytic converter okay?
