Can someone tell me where this hose routes to
 

I have been looking at pics of Euro S motors and I think my top vacuum line on my WUR is routed different than others. I have it connected to the back drivers side of the throttle body. Where is it supposed to go?http://forums.pelicanparts.com/uploa...1303590299.jpg

I am going to post pics of all vac lines. Please let me know if you see something wrong.http://forums.pelicanparts.com/uploa...1303591003.jpg

On my US 79, the top vac hose on the WUR hooks up to the 2nd port on the right front of the throttle body (should be 1st port right front on a Euro) and the bottom vac hose on the WUR hooks up to the left rear port on the throttle body.

I've found this link a great resource when it comes to vac hose routing, check out page 27.

Thanks-I'll check the resource. When you say rt front do you mean passenger or driver side(US)? Front towards the nose of the car?

Dude, that network is all wrong!

I'm kidding. Your engine bay looks so good! Pristine! Gorgeous! I love a clean engine. :)

Mine looks like this. I don't think it's the same as the pass front ports are vertical to each other and go into the vacuum limiter.http://forums.pelicanparts.com/uploa...1303612740.jpg

All references to left and right are from sitting behind the steering wheel looking forward.

So the top hose to your WUR, with the engine running does it have vacuum at idle or only at part throttle?

I'll check. I got this great photo from RL.http://forums.pelicanparts.com/uploa...1303642380.jpg

Nice diagram.

Do you have K-Jet manuals?
There is one with some pretty good troubleshooting logic trees.

Do you know if your injectors have clean screens?

I have the troubleshooting guide somewhere. The injectors were supposed to have been tested as good. Dr. Bob pointed out I have the wrong coil(which was leaking wax) so I may have my running issues fixed when I get the right coil.

So it looks like you had the WUR vac lines reversed, RL pic jibes with my previous post. Top WUR line to first vac port on right side and side or bottom WUR vac line to left rear port on throttle body.

With the vac lines reversed, it lowers control pressure which would've made the mixture rich.
