No not yet.
Is it a diy job with a few spanners 'cos i have no idea about that?
An online guide somewhere maybe?

If they do colapse is the engine still able to run smoothly at times and/or go from that to misfiring like turning a lightswitch because that what its like driving it.

The long hose up to the ECU is a favourite as it has to pass through the skuttle and can get compressed there.

just swapped the vacuum pipe...no difference

So far vacuum pipie, spark plugs,coil pack, ecu relay (doubt it will be the fuel pump relay or ignition leads) have been swapped.

Any other ideas?

I think I said before, it misfires accelerating (even less than 1/4 throttle when properly warm sometimes) from low revs but if i lift off then put my foot down again it goes fine

it will do it pretty much any time i floor it though, goin from low or high revs, hot or cold
