93 90CS Stalling

[Daniel Adams <doasc@yahoo.com>]

This is a continuation of my original Automatic/Stalling thread.

Basically, I removed and cleaned the ISV, which didn't resolve the
problem.  At this point I ordered a new ISV ($188) and installed it. 
Like the cleaning, it seemed to resolve the problem for a day and then
the stalling returned.  To revisit; when the car shifts out of the
lock-up converter to 3rd, the car has a tendency (60-70% of the time)
to stall.  If I can touch the gas as I slow down or pull the gear
selector into "3" before the automatic shifts the transmission the
problem is avoided.

The next step I guess is to investigate the vacuum system.  FWIW, a
while back I had read about the vacuum reservoir (6-7" black plastic
ball, located front left between heads) leaking.  I took it off and
pressure tested it with no problem.  I also replaced the O2 sensor and
had the cat-converter and fuel injectors replaced under recall.

Any ideas, would be appreciated.
