see what happens with super unleaded fuel first, but failing that

go over the fuel system, do a fiter change, check injectors spray properly and all the seals/top hats are good, check the metering head flap isnt sticking

was the wur tweaked when you checked the fuel pressure? they have been known to go wrong after being fiddled with!

think the guy did say somethink about the wur but im not sure what that is i will fill up with super and mayby just increase fuel mixture a tiny bit well il see what it says on the emiisions machine first

cheers for your help m8

no worries, your aiming for 2 - 2.5% on the emissions if you didnt know 

btw the screw is fooking sensitive

How much was skimmed from the head as if the compression has been raised that might be a issue.

Yes would be a good move to start with.
