86 5kcst Idle problems....

["Michael R. Douglas" <mrd@gte.net>]

I have a 1986 Audi 5kcst.  I have cleaned-out the ISV valve and had the
IDLE ajusted by someone at Audi.  But, now that the HOT weather has
come, whe I start the car and turn on the A/C, it idles down and cuts
off the engine.  Sometimes it just idles down, and no engine cut-off. 
Where is the general idle ajustment located on this engine??  Any help
on this matter would be great!...
