Technical problems with my MK1 Uno Turbo

[oldskoolmk1unoturbo]

I still have a spluttering problem with my Uno Turbo I have replaced the HT leads now and still the same, basically when the car is warmed up on boost its hesitating to go,

I think i may have found the problem being with the FSE boost valve, basically the car does idle a little rough and i noticed there isnt much vacumm showing up on the boost guage, so i disconnected the vacumm pipe from the FSE and the idling went up and so did the vacumm on the guage,

I blew down the pipe going into the FSE and its slightly not holding pressure, does anyone know what this pipe going to the FSE actually do? and can i leave it disconnected? i dont wanna drive it with it disconnected if something aint right, I've attached some pictures so you can see the before and the after

Mark.

Check the state of the plugs when its been idling mate

If they are wet then it sounds like a too much fuel is wetting up the plugs (causing a uneven ldle speed)

keeping the vaccum pipe off will not get a vaccum to the diaphram in the FSE so no pressure regulation will take place (it will run really rich and not get the correct fuel pressure at the RPM levels hence the hesitation)

I could of left some info out of that, Citation please! lol
