Hi

I really cant figure out what hose is missing here?
1 goes to the airfilterbox
1 goes to the bypassvalve (hope Im right?)
But what about the third connection here? Got input that It might be a cable that goes from the manifold intake. But cant find were.
Any help is appreciated. I have been googling so much now that I cant come up with more ideeas to search for.
I have a idle stall problem wich occurs everytime and not from time to time

 

Do you have an automatic? That doesn't sound right at all. These might help you:

4 connects to the brass nipple on the bypass valve and 6 connects to the bottom of 4

13 connects to the bottom of the fuel pressure regulator and the intake manifold. If you have a boost gauge it will be spliced into this line too

1 goes from the brake booster to the intake tube and if you have an automatic there is a line that branches off and connects to the intake tube. There is also a hose that connects to the valve cover on the drivers side and connects to the intake tube.

 

Looks like a JCW Factory intake hose vacuum line.

Would be very thankful If you would read the update.

You are welcome. I would inspect all the vacuum lines for leaks, sounds like MAP and vacuum problem.
