Dear Robert,

Thereâ€™s some black smoke coming out of my 2018 Nissan Kicksâ€™ exhaust. My friend has some mechanical knowledge and said this could be down to a problem with the fuel pressure regulator: what do you think?

Thanks,
Jenny

Hi, Jenny!

Black smoke coming from your 2018 Nissan Kicksâ€™ exhaust isnâ€™t a cause for immediate concern. Some cars produce this for a short while after you start them up.

If the smoke persists, however, itâ€™s likely that your car is burning too much gasoline. This problem could be caused by a bad fuel pressure regulator.

This component regulates how much gasoline gets to your Kicksâ€™ engine. If the pressure falls low, your car wonâ€™t start. But, when itâ€™s too high, your vehicle will be over-fueled and produce white smoke.

If your car is over-fueled, itâ€™s probably also running rough and delivering poor gas mileage: so these are symptoms to look out for.

This problem could also be caused by leaky or clogged fuel injectors. My advice is to bring your vehicle down to our Service Department and let the Technicians inspect it.
