I was wondering if any one has a diagram for a 1983 Australian Delivered 280ZX I’ve done an exhaustive search and there are no diagrams on how to correctly connect the vacuum lines and the most annoy thing I’ve been having so far is that the manual doesn’t show the type of BCDD that is in my vehicle it shows the manifold intake and the vacuum line but I have a vehicle with an additional vacuum line. Also there is a component I think its called a Vacuum Control something but there is nothing in the service manuals about it either. And its all around the same thing no vacuum line diagrams.

Is there anyone that could help I'd appreciate it. Xenon130 didn’t have what I needed.

I'm not to sure if I'm just not seeing it in all the service manuals but I cant find anything relating to these issues.

Thanks in advance.

 

Welcome to ZDriver!

Could you post a pic of the vacuum line and "vacuum control something" in question?

Also, check out http://nissan4u.com for all the factory diagrams & schematics.

 

That site you posted I must say google did not leed me there.

It part number 9.

I'm going to have to decode that picture. That what i've been looking for but its going to be hard to work out were stuff is going.

If I could maybe have a little assitance working out this pic.

 

Looks like #13. Vacuum switching valve. Looks like its T-d into the throttle body and off to the charcoal canister.

 

Does this look right and can the vacuum advance being faulty cause the car to hunt for idle?

 

Cant really tell in the drawing, should work like that...Did you try to unhook the vacuum advance, does idle change?

 

here ya go
