Pulled Codes.... Please Help

[mpj76]

Don't know about the harness, but a vacuum leak will cause what you described. I removed my smog pump, pinched off the inlet at the H-pipe, and removed all the other plumbing. Car runs fine, no codes.

I have a question about the vaccum lines. The pipe with the 3 other pipes coming from it, what vaccum lines connect onto it? And then there's this other pipe thing that is on the passenger side of the intake near the back of the intake....there's a hose that connects from one side to the intake and then what....what connects on the other side? There's also some small pipes that are both sides of the crossover from the throttle body bolt base to the part where the intake curves, what goes on those hoses? It may sound confusing. Here's a pic of what it looks like.



It's the two green pipes and that orange one.
Do I have the correct setup for the dotted red line hoses?

For what it is worth, the large vacuum source you wondered about is the one I have routed to the PCV. The tree lines go as you indicated and the one you have going to the PCV, I have blocked off b/c it once went to another vacuum source.
good luck.
