no idea what the silver thing could be, post pics :)
 
check (and ideally replace) all of your vacuum hoses, for sure one is cracked or split.

the UIM (Upper Inlet Manifold) is indeed the big silver thing at the back. It\'s attached to the throttle body where the intake elbow attaches from the intercooler.

When you\'re removing it make sure you undo all the coolant hoses first (IIRC there\'s too) otherwise you might damage them. Get a copy of the workshop manual - tells you how to do it in there.
