Well, I've got another 325 throttle body from eBay - it's a later model one, so it has no bypass screw on the top like my original has, and has the large rubber sleeve over the outlet on the bottom of the body near the TPS.
Here's what's odd - the small metal vacuum hose elbows on the right hand side - it only has one. There's a hole for and a second, but it's more of a socket then a duct, as it doesn't go all the way through to the interior bore of the throttle...
Is this like the ones you have? If so, how does the plastic 'air pump' and vacuum check valves get plumbed in?
