I have an '85 1.9l that likes to stall when braking quickly at a stop sign
or red light when cold.  If I push in the clutch too soon, it will stall.
This usually happens only in the first 15 minutes or so.  I get a blip on
the tachometer, usually a red light (battery/alt) and it stalls.  Cold
starts require some fancy footing to keep it idling.  I have replaced the
idle stabilizer and gone over most of the FI system.  The throttle switch
is correct.  The temp. sensor was replaced.  The AFC was replaced along
with all vacuum lines.  The aux. air switch is OK.  It seems ignition
related because of the spike on the tach.  I may have the idle screw/CO
settings too far off for the idle stabilizer to correct.  It seems like the
stabilizer is trying to keep it going, but can't compensate enough.  Once
its warm, the idle is fine.  If I ease into the stop and only use the
clutch once the rpms are down to  idle speed, it is OK .    I do have the
timing advanced a few degrees--it seems to rum better there. I should
double check that first.  Someone suggested coil because of the tach spike,
but it runs ok once warm.  Any suggestions?
