Does it do it all the time?

Here's one way to determine if you have an electrical issue. All cars run on default settings ( cold ) until the engine warms up, then all sensors, etc come online.

I'm not familiar with the Corsica, but if it ( and it most likely does ) has a Mass Airflow Sensor, try disconnecting it with the engine off, but warm, restart and try to recreate the conditions when it stalls. A bad MAF sensor will cause stalls, but run fine at idle, maybe give you a little bit of a lope. Most likely this isn't the cause, but you can at least rule it out easily enough.

What happens when you pull the connector off of the MAF sensor ( it's directly behind the aircleaner ), it goes to default mode..basically bypasses the signal it would have normally get.

Could be a vacuum problem, RobRich has a good point too..how old is the battery... any Batteries Plus ( if you have one ) will test the battery for free, as a few other shops may charge you a couple of bucks...it's worth a check.

Give the easy stuff a shot, and if something is still wrong, tell us what you did, and any other relevant data....
