High idle - Tried everything :|

I also game an issue with a very high idle on my 1.6 k-jet, I replaced some split vacuum houses which helped but I reckon it might be this little piece that is sending it off. 
Anyone heard back as to the supply of these or if there is another part I can fit? 

Cheers  Sam

No answers back yet, I've left my order open until stock is avilable - either that or I'll see if i can get hold of a second hand part but then no guarantee how long to will last.

There's one on eBay at the minute but I don't know whether to chance it.  Need to check by blocking off the hoses that come from the manifold and check if the idle drops.

Anyone who see's this, what/where is the AAV? I've had a look in a few of the guides but the diagrams aren't working.

Thanks, Sam
