RE:5kcsT cold start problem

[Albert Ng <alng@purdue.edu>]

Hi AudiFans,


I have exactly the same problem with my '87 5kcst. I've cleaned and
checked the ISV and the cold start valve. I've also adjusted the idle fuel
mixtures and idle. I've found that it get a little better after I adjusted
the idle fuel mixture, but I still need to tab the gas padle for a second
in order to hold the cold start idle during morning start up. 

Will a bad warm-up regulator cause this problem? Can anyone one help us
out?



Thank's for the time

Hello everyone-

 Well, after 4 months of almost trouble-free ownership
my Audi starts developing a small problem.Here is the deal.
When I try to start engine in the morning and  outside 
temperature is in low 30s or less, it starts right away, but 
runs at very low (300-400) RPMs and then dies in few seconds. 
I have to push the gas pedal slightly to keep it running. After 
approximately 1 min I can turn the engine off and start it again,
then it idles fine. It starts fine when warm and hot,and car 
runs great overwise. I am wondering if anyone else has experienced
this problem or have any idea what's wrong. 

 The another question, I've never seen more then 1.3 bar boost
pressure,even if I push the car really hard.Is this normal for
stock 5kcsT?
             Thanks in advance
                               Eugene.
