Hi guys.
OK got the four done solved the brakes and non starting issues and it's running ok but for the fueling it does seem a bit heavy on fuel.
It's been rebuilt and forged and has only covered 160 miles on the new build.
it smells very rich when running and the blitz shiny tail pipe is black and sooty.
when I rebuilt it it also had the injectors overhauled at the same time and is not showing any codes so it appears to be ok except for fuel consumption and a sooty pipe.
Any thoughts guys
Regards Barrie

Solved :
It was a faulty distributer making the plug on N2 miss fire changed dizzy and a seems good now
