Re: 5KCSTQ - Bad Cold Start==>Bad Hot Idle

["CHRIS AHOLA" <aholact@songs.sce.com>]

     Mark,
     I can sympathize with you.  My '87 5KCSTQ has cost me over $5K in 
     repairs in two years and a lot of arguments with my wife.  She 
     thinks the car is a piece of "SH!T" and reminds me every chance 
     she gets that most everyone I know said not to buy an Audi.  But 
     every time I remind her that we own a superior German engineered 
     luxury sport sedan something else breaks.  
     
     Anyway I had a similar problem.  It turned out to be a bad 
     thermoswitch that was part of the idle stabilization system.  The 
     thermoswitch had a single wire running to it and was mounted on 
     the side of the engine near the front.  
     
     Good luck,
     Chris
     
     
All:
     
Here are my/her symptoms:
     
My '86 5KCSTQ generally takes three cranks (1-2 second in duration) 
to start when cold.  Sputters for a bit (5 seconds or so) and then 
idles smoothly @800-900RPM.
     
After a "long" highway run (1 hour @80-85MPH) she will idle pretty
well but between 500 and 600 RPM when stopping, such as at a toll-booth.
     
If I shut her down after she's hot (please, please leave it alone) and 
restart before she cools off (oh go ahead) the engine will seriously 
stumble (below 200RPM) and if I don't give it gas will die.
     
Help!  I'm catching it from my wife as she does not appreciate the 
finer points of a Quattro.
