02 Sensor Circuit Slow Response (Bank 2 Sensor 3)

The oxygen sensor on Bank 2 after the third catalytic converter is responding too slowly to changes in exhaust composition. A sluggish sensor prevents the engine from quickly adjusting the fuel mixture when driving conditions change. This results in delayed response to acceleration, poor fuel economy, and rough running during gear changes.
