hi all , need some advice , when starting from cold the x11 runs on 3 cylinders , doesn't matter if im using the cold start or not , after 1/2 mile the fourth cylinder cuts in . I have ordered a fuel pressure regulator in hope of curing the rough running at low revs , so im sort of hoping it will sort out the starting issue or do you know whats wrong , will be most grateful for any help

Just swap the plugs around and see if the same cylinder doesn't fire. Try running some Redex injector cleaner through it, you might have a blocked injector. I'd also try seeing if you get a good spark to the offending cylinder. You might have a fault somewhere along the HT lead, maybe corrosion or a damaged cable.
