Im "cleaning out" some vac hoses and unneeded stuff, like EGR, and EVAP :waveybiggrin2: Im trying to figure out this thing. Looks like some sort of vac adjuster/regulator? My Haynes book says nothing about it. Anyone care to inform me?

It skrews into the IM, the two small hose barbs go to a little switch or something on the firewall. The big barb hoks into a metal line that bolts to the back of the IM and runs vac hoses to the P/S pump and one to the TB for the idle speed controller. Im assuming its used to adjust the amount of vac going to those instruments.

Looks like the A/C idle up valve.

Ah, ok. The switch on the firewall closes when you turn AC on, building pressure in the pictured thingy above, it then opens the larger line up with a diaphram i assume, and changes the vac on the idle speed control. Thanks Hook
