2005 Mercedes Benz E320
2005 Mercedes Benz E320 mileage: 35,000. Would a bad oxygen sensor before the catalytic converter cause my car to hesitate during acceleration in low gears? What causes these to go bad?

It is not likely for an oxygen sensor to cause the poor running you are experiencing. It sounds more like a clogged fuel filter or a failing fuel pump. Oxygen sensors eventually burn themselves out due to the heat of the exhaust.
