So today I started investigating the issue and it looks like I've found it .. If I blow into the vacuum lines you can hear a hissing as it's coming out somewhere. .
A little more searching led me too the actuator.
If I blow into the vacuum port on the actuator you can hear it leaking from inside ..
So that has possibly found the issue. Won't know for certain till a new one arrives tomoz. .
I've also De modified abit more . For some reason it had a tubular manifold fitted. I've removed it and fitted a standard manifold ..
Also noticed the tubular manifold had cracks in it .
