RE: 4ks OXS-system connector problem?

[christopher_bender@fmc.com (CHRISTOPHER BENDER)]

     The little white two pin connector you mention is not supposed to be 
     connected to anything.  It is for hooking up a duty cycle meter when 
     adjusting the base idle speed.
     
     So, sorry to say, you should keep looking for the source of you 
     problem.

     Hi all,
     
     So, I'm just starting to get a chance to poke around the motor of last 
     month's
     '86 4ks acquisition to cure my horrible part-throttle stumble.  Also, 
     now that
     its cool (50-60F) I have to wait at least a full minute before I can 
     drive off.
     If I feed it _any_ throttle, it will stumble and/or die.  Just won't 
     rev above
     idle at all.  It does however start and idle perfectly.  Seems to be 
     going very
     lean, I'd guess.  
     
     Anyway, my initial poking around revealed a connecter near the intake 
     boot 
     that wasn't connected to anything, but was broken and corroded.  At 
     first I 
     was sure I'd found the problem, but I then realized I could find 
     absolutely 
     nothing to plug it into.  I pulled out my newly acquired, but as yet 
     unread
     Bentley and believe I have identified the connector as T2A.  Its a two 
     pin
     white plastic sort of Molex looking afair.  That, its location near 
     the intake
     boot, and the wires coming out of it (G/R & B/R, with one of them 
     actually
     being a pair, can't recall which) is how I identified it.  If I'm 
     right, both
     go back to the main ECU, but the dual-wired terminal pigtails back to 
     something
     called an idle stabilizer valve.  
     
     I'm not familiar yet with the wiring diagaram conventions in the 
     manual
     (like, of what use are track numbers and what about those numbers that 
     go
     across the bottom of the pages, sequentially?) but it appears that 
     maybe
     this connector is supposed to be unattached.  Might also be that it 
     goes to 
     a connector on another page I haven't found yet and I'm just not 
     interpreting
     the diagrams right yet.
     
     I'd be mucho appreciative of any help specific to this connector, its 
     relevance
     to my problem, or on Bentley wiring diagram interpretation in general.
     
     Thanks bunches.
     regards
     roger
