Peugeot 3008 Running Rich

My 2018 Peugeot 3008, gasoline engine, is throwing some codes. Mileage is at 200618 km. Seems to be running rich – reduced power, check engine light's on, rough running, guzzling fuel, and jerking when accelerating. Air filter's new. Could a dodgy injector cause all this?

Running rich, eh? Check engine light is a clue. Have you scanned for codes? An O2 sensor fault might also trigger similar symptoms. What codes are you seeing?

Yes, I scanned it. Getting codes pointing to a rich mixture, but pinpointing the exact cause is proving tricky. If it is the injector, would that explain all the symptoms?

A defective injector definitely explains all of it. Too much fuel will cause a rich mixture, hence the reduced power, rough running, and increased fuel consumption. Jerking under acceleration fits too. Time for the workshop, I'd say.

Cheers. Dropped it off this morning; you called it. Bad injector. Quoted 515€ for the fix. Thanks for confirming my suspicions.
