Hello everyone,

I have a navara yd25 that has black exhaust smoke when accelerating and poor fuel economy. Accompanied but nothing else. Excellent acceleration, no fault codes no nothing.
Note that i had checked the diesel injectors, cleaned and eventually replaced the maf sensor, replaced fuel rail sensor cleaned the airfilter.


Please help 馃槶
