After a extensive search to find a diagram for the modified vaccum hose diagram for the NA, I have only been able to find the diagram for the tt. I brought my z with the eg and aiv. If anyone has any insight on this, please let me know

Oh, and for the PRVR, you would just loop the two fittings together, like here:

The silver u-shaped hose. Be sure there's no kinks in the hose.

Fixed the vacuum lines & It's a night & day difference. I never would have thought that the vacuum hoses would make such a big difference. Thanks for your help BIGTDOGG
