Subject: Throttle Body Question

 
 
 
  I have an '88GL, 2.1L WBX, manual tranny. The fuel system is Digifant. 
 
The throttle body lays transverse over the engine. From the Right hand 
side of the firewall, through a hole, there is a plastic tube that comes 
across and attaches by a little rubber hose to a nipple on the forward 
(firewall) side of the throttle body. The hose is rotted through and 
needs replacing. 
 
I cannot find a picture with that nipple showing, nor that plastic tube. 
May have just missed it in Bentley, but what is the purpose of that tube 
to the throttle body, and where does it go/come from through the 
firewall? How does it affect engine operation? 
 
Thanks, 
 
John
