CHEVY OXYGEN SENSORS

2001 Chevrolet Silverado

Engine Performance problem
2001 Chevy Silverado V8 Four Wheel Drive Automatic 170000 miles

Service engine light on. Code oxygen sensor. Tried BG44K gas additive, Ran well for 2 days then died and wouldn" t start. Can bad oxygen sensors cause an engine to suddenly stop and not restart? Truck has 4 o2 sensors.

No, but a clogged catalytic converter can and a faulty cat. Converter will often throw the oxygen sensor trouble code as well.
