S**t Petrol Consumption/MPG

[DavyGray]

I have a Micra K11 2001 Sport 1.0L and the past month my MPG/Fuel consumption has gone from okay to s**t...

I do roughly 300 miles a week and off a full tank i used to get 200+ miles out of it. I do use the A14 and A12 regularly hence the high mileage.

Now im getting 150-170 (if im lucky) out of a full tank...

Would it be worth a new lambda sensor, new spark plugs and cleaning my MAF sensor? Or would it be something else?

leaking injector or cold solder at maf is most common problem at micra wich causes very big comsumption..
Start with them. If not, unplug lambda and see if that makes any difference..

If its a coilpack engine your out of luck. You cant resolder the maf. But they still die quite a lot.
