[s-cars] possible ignition problem

[binh douglas]

Has anyone had this issue?
    I have a '95 s6 avant. When the car is at idle, the rpm's 
occasionally dip below 1000, and pop back up. This doesn't happen all 
the time, but occasionally.  However, there are times when the rpms dip 
so low that the car stalls. This only occurs when I am coming to stop 
before the car has warmed up in the mornings. I live in FL, so it 
doesn't take long. Another symptom its been having is under high boost, 
it seems to sputter a little as if there is a possible leak somewhere 
or as if the car is mis-firing. If I back off of the gas a little, it 
goes away. the problem seems to be amplified when I use the A/C. Does 
anyone have any suggestions as to what this might be?

Thanks,
Binh
