Start with the basics
- cambelt cover off & check that the cam timing is OK
- spark plugs out & do a compression test

I did notice the fuel pressure wasn't too good when doing the cam covers, with it being the front two cylinders i.e furthest away from the pump???. I have a spare filter so will throw that on in the morning just for the hell of it. Advice taken on board anyhow  :y

I reckon the seals on injectors are shot-I had that on my 2.5 on number 5 iirc and that through up misfire + misfire code ???

SORTED.....new fuel filter helped, replacement bellow on the bagpipe helped more as it was split, then I  spotted an open vac pipe from the lower vac reservoir so plugged this and it is firing on all six!!

looks like the hbv is leaking but thats easily sorted!
