Disco 1 '96 V8 EFI vacuum / intake pipes

Hi guys,

Sorry if this question has been asked before, but after searching the forum for the last couple of days I have found nothing that's exactly what I'm after...
Where can I find a diagram of where all the different vacuum / air pipes connect to on the intake manifold
(?is the intake manifold call the Plenum chamber?)
On the bulkhead end of the intake manifold is a really small open ended pipe, that's sucking air in and causing the engine to idle at about 1200rpm, when I put my finger on it the idle revs drop down to about 600-700 or there about....

Any advice on which hose should be connected onto that little pipe end, and where it should go to? or if it should just be blanked off?

Please see picture below...

Thanks

Loz

A short length 9" approx of tube from the idle control valve (your picture) to the fuel pressure regulator which is a small round sealed unit on the fuel rail at the other side of the plenum, and lower down by the throttle linkage, just push the tube back on the nipple. Simples
