Cutting out when cold

Hi,

My '84 gti cab keeps cutting out at junctions when warm. I've had a scan through haynes but it's rubbish. I'm thinking it's the auxillary air valve located near the oil filter but don't know how to test it.

Any help??? :dontknow:

How to test it:

1. Start your car from cold
2. Locate the pipe connected to it which bends around and down the back of the inlet manifold
3. Squeeze it shut and your revs should drop, this indicates the valve working, which I believe it should be open.

Then as your engine warms up it should close (I assume I got it right way around lol)

So you run the car, drive it for a while till it's warm and repeat the same steps, this time your revs shouldn't drop, if they do, then it's kerry packared.

I hope this helps.

It's out fo a K/KE-Jectronic book I borrowed from a mate when I thought mine was shot.
