Well, yes, I've been told that some sort of "upstream O-2 sensor" is defective, but I've just ignored it because my friend told me that that would have nothing to do with the car stalling out. He said that's just one of those "environmental emmissions" things...which won't affect performance of the car. Was he wrong on that...?? ---confused---

probably your car its equipped with 2 oxigen sensor one before and another after the catalitic converter...
and yes, he is wrong.. the oxigen sensor work with the on board computer to deliver the right amount of gas to the cylinders, if its running to rich the sensor reads the oxigen quantity and leans the gas and viceversa...
if your sensor its not working right start replacing it and see how it works.

good luck!
