Hey guys, just a quick question for ya's,
Just wanted to know, i have a jdm bigport 4age and the tvis has been removed. There is the two bungs on my manifold; one on the throttle body and one on the manifold (just after the throttlebody) then there's one on the charcol canister and one under the throttle linkage that looks like it has something to do with cold start? There are no vacuum lines to any of thease and just want to know where the should be hooked up it? My 4age book doesnt have anything about the vacuum lines.

Cheers, ben.

also, there is the one on the black bung which goes to the fuel reg that is blocked off.
Its hunting when at idle, when it decides to idle.

Hope these pictures are of use for labelling.
I also need to know what to do with the bottom part of the throttle body. As I know it would normally have coolant going through it. What part is for the idle control?
Anyways here are the pics

Below the throttle body, the two 8mm lines pointing downwards are for the coolant in and out. The 8mm line pointing out front is from aircon idle up valve, the two 6mm lines pointing out to the front are for power steer idle up. On top, the 3mm line lablelled N is for AC idle up control and the 3mm labelled P or C is for the charcoal cannister.
