The engine runs/idles perfect, Idle is about 600 smooth RPM on the
dash tack. But....when underway, and you come to a stop or even just
decelerate for a turn, letting engine drop down to idle, then it
stalls often. What would cause bad idle when car
underway/decelerating, but checks good when sitting still? Seems like
a vacuum leak would mess up the sitting- still idle, also. thanks,
Geronimo

And adjust it if need be, a too-closed idle stop will cause the RPM to dip
when the throttle slaps shut, with an automatic this can cause the engine to
stall.

I had a similar problem and after MONTHS of trying everything
imaginable it turned
out to be a crack in the distributor cap. If it seems to be worse on
rainy days I
would bet thats what it is. Good luck!
