Re: missing hose

     Man, your mail is tough to decipher, but here is what I make of what 
     you are describing.
     
     Confirm electrical connections to things like the idle air stabalizer 
     and O2 sensor, and knock sensor, but it sounds like the one electrical 
     lead you describe is for a test harness for diagnostics.
     
     As for your vacuum lines, I hate to say it, but unless I could 
     visually see it, I have to reccommend picking up the Bently Service 
     Manual for the car which has diagrams showing connection points.
     
     The tube you described is a test pipe for emmisions etc.  This tube 
     SHOULD BE plugged, or as it came from the factory with a rubber cap.  
     I had one of these come off on a GTI I owned and it ran awful.  I 
     capped it with a large rubber vacuum cap and hose clamp.
     
     Hope this helps,
     -Paul

found a vacumm outlet in my 8v 85 but there was no tube connected to 
it????   i found it at a vacumm pump that is located in the left of the 
car behind the engine, just below the hood.  there were two outlets the 
top one connects to the right of the y connector that is feed by a tube 
from the firewall and then goes out to the trottle control pump(turns out 
that the hoses were cracked at the tip and were leaky....  replaced it and 
the engine response was so much better!!!!!!) . the bottom outlet however 
connects to nowhere?????????  also noticed a circuit connector that is not 
plugged in, it is located below the y connector about halfway down to the 
ground.....  looked all about inside the car but the was other vacumm 
outlet or circuit connector unconnected....  it sure beats me where they 
go........
     
also notice that there is a thin exhaust outlet that is not plugged..... 
it is located just behind the engine where you fill the crankcase....  you 
know what talking i am  about?????  it is a thin tubing that connects from 
the intake manifold (i think?!?!?!?  could not find it anywhere in the 
damn haynes) and goes up until the engine level.....  it looks like a 
tubing for a dipstick......  does anyone knows what it is for????  what 
will happen it is remains unplugged......  it took a plug from my gal's 
passat and put it into my scirocco.......  it sure kept the car real 
quiet........  it now has a real nice purr......  instead of the rattlely 
sound before.......
