The snow behind was coated rather thickly in an Amber coloured oily layer, suspiciously like neat deisel.
It always smokes like this when held on the throttle when cold, once it's warmed up it doesn't seem to smoke, but the exhaust always smells very strongly of diesel.
The car is drinkng derv too, like 1/8 of a tank for 15 miles running about.
It's done 140k miles... So the question is, what's wrong with it? Injectors, MAF (Mass Air Flow Sensor) or something else?
