Let me see if i can find my file i wrote on setting up the avac system.
Its on here pug306.net some where.
Do you have the metal pipes for vacume running across the top of the engine?

IIRC I used 4mm on mine but it was a few years ago now so not 100% sure.

This pic shows the vacuum pipe coming from the ecu to the white filter, then on to the metal pipe on the inlet manifold:



The second pic shows the inlet manifold, the big pipe on the right goes to the big tee piece that is connected to the vacuum pump and brake servo, the middle one connects to the other end of the metal pipe from the ecu and the one on the left goes to the fuel pressure reg on the fuel rail:



The third pic shows the top of the inlet manifold, the feed from the inlet manifold comes up from underneath on to the fuel pressure reg, there is also a small tee piece that connects the two vacuum solenoids together, the vacuum feed goes under the manifold and round to the side where the electrical solenoid is mounted to the side of the cylinder head:



The last pic shows the electrical solenoid and the big tee piece on the side of the head. The electrical solenoid can't really be seen though partly due to a leak I had covering every thing in crappy water that is a sod to get off and just because there is so much stuff there. Basically on the electrical solenoid, the vacuum connector pointing to the front of the car has the vacuum feed from the big tee piece connected to it, the outlet just above it pointing up has the vacuum line to the solenoids on the inlet manifold connected to it and the outlet on the back of the electrical solenoid is left open:

Yeah IIRC when mine got unplugged it wouldn't idle but would rev ok if you kept it going yourself.

LOL the ICV is a right b*tch to get out without taking the throttle body off. it is possible though just takes a lot of patience!

The part number is: 4575 19 They call it an Amplifier Valve and it is £25.92 apparently, according to service box anyway.

I may have a spare one about if you want it (that is assuming I've still got it and it's still in the box where I put it)
