Can someone tell me where this hose routes to: 82 Euro S
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?

Posting all vacuum connection pics. Please tell me if you see something wrong.

I'm not sure about the routing... (I have to re-do my vacuum lines shortly too, so thanks for the thread)... BUT..... be sure you grab this washer before you pull those intake plugs!! Yikes!

Thanks, but that washer is actually a ground connection. It has a wire attached to it. These are old pics by the way. Its all together now.

My WUR has two side vacuum connections(one on each side) and the one on the top. I see the top and a side connection in the info you provided. Does anyone know where the 3rd one connects. I have it teed into the top distrib. connection now.

All the WURs I have seen have two vacuum connections. Is your perhaps made up from parts from different versions?
Are the two side ports at the same height? i.e. on the same component part of the WUR.
Have you tried blowing into the top port and seeing if your breath comes out of one of the side ports? If so, those two should be T-ed and treated as the top port.

This is a diagram of the insides of a 928 WUR. It is different from the diagrams in the books.
You can see that the vacuum connection is in the middle section.
I would expect your other port (on the lowest section), on the left side of the car, to go into the main space of the WUR.
Check that blowing in the top port blows out of that one to be sure. Blank that off of T it into the top port.
At the end of the day, check that the Control Pressure responds to changes in the intake vacuum as in the workshop manual.

I did. Still ran bad. I think I tracked the problem down to the car having the wrong coil(with Dr. Bob's help). It was leaking wax. I am going to get one from Roger along with replacement plug wires. Can't wait to see if this is the all elusive fix.

this sounds like a long shot once the coil is 12 volt and connects up ok cant see it causing the motor to run on 7...think i read somewhere in one of your treads that you had recently preformed a compression test and even though you got a bad result dry you then put a squirt of oil in each cylinder and then got a good result.alarm bells went off with me!!!!!! this would proof piston/cylinder major issues.and lack of compression IS the problem....but maybe i picked that one up wrong???
