@mahamatyoussouf what exact year, model and engine size is your Hyundai? What have you checked? How does it currently perform? How much fuel is it consuming?

@mahamatyoussouf, c'est quoi l'année, le modèle et la cylindrée exacts de ta Hyundai ? T'as vérifié quoi ? Comment elle roule en ce moment ? Elle consomme combien de carburant ?

Here's a video that shows how to replace the downstream O2 sensor and another video that shows how to replace the upstream O2 sensor.
