Bad plugs or plug wires. Blown head gasket or burnt valve. A compression test will eliminate burnt valve or blown gasket.

It means the computer is detecting a misfire on those cylinders, the most common cause is worn spark plugs or spark plug wires. I would recomend replaces both then clear the computer codes and see if the service engine light comes back on.
That would be the sensor after the catalytic converter.
