Well my car idles kinda crappy and I was thinking that I had a boost leak. I checked my vacuum hoses first and found a hose coming from the intake manifold that wasn't connecting to anything. The open end of the hose had a clamp still on it so I know it goes somewhere. I don't really have a clue to where the hose connects to. At least not yet. I'm planning on removing the battery so I can get a better look behind the engine bay this weekend.
Anyway, I downloaded the service manual off of scribd.com and found a vacuum hose diagram. What does the A, E, and P stand for in the circle?
Here are pics of the vacuum hose that is disconnected and have no clue to where it goes to. After looking at the diagram, it seems to me that it goes to the by-pass valve. What does the by-pass valve do and more importantly, where is it located?
