1. The VSS. The PCM knows how fast the car is actually moving and that it is not at rest. It idles up and runs rich when "idling" & moving. A richer mixture is more likely to stall due to a sudden air pressure drop.

2. "Any" car will be more susceptible to stalling when coasting if you hit the brakes or sustain a panic stop. That's a given for any car regardless of computer control or not. Manifold vacuum is vacuum.
