Engine Performance problem
1992 Chevy Caprice V8 All Wheel Drive Automatic
when I pull up at a light or stop sign my car idle down and cuts off will it be the oxygen sensor or fuel pump?

I question if either the pump or O2 sensor is causing it. Has the check engine light come on? Have you checked for vacuum leaks?
Let me know.
