Fixing the P0171 error I found 3 vacuum hoses broken and disconnected. I need help in figuring out how to connect these. The attached picture (from my 2003 SLK 230) shows the line from the Change Over Value (light green), a transparent tube going into the firewall (pink) and a rubber hose from the intake manifold (orange). The image of the Vacuum Map on the inside of the hood, does not describe all the lines. Is it missing a "Y" connector, a check valve, etc. Any help or a picture would be greatly appreciated.
