Eureka!

[Guest hughie]

:blink: Finally solved the emissions problem, an air leak on the vacume pipe from the lpg vapouriser to the air intake manifold. Took the car to an old fashioned mechanic as opposed to a technician, found the fault in two minuite flat by listening out for any hisssing niose. Couldn't hear a thing myself, I guess theres nothing like experience.

All emissions are now normal, if i would have let the ford dealership have there way they would have striped the injectors out and replaced them, as there top technician was certain one of the injectors was leaking how wrong he was.

 

Thanks to sa intruder for all your help.
