Hi,
my name's Antoine and i live in Spain. I¡m French but been in Spain for 15years.
I have a 100nx 2.0 and a problem of over fuel consumption. About 16liters per 100kms ( Sorry but i don't know in mpg...

) in town.
I have cleaned, checked and changed everything.
I have found the other day that you can regulate the co2 in the air flow meter, by drilling an access hole to the screw.
Do you know how this goes?
Many thanks...
