SOURCE: 02 kia fail smog high nox
if the engine computer says that you have a slow O2 sensor what it means is that the sensor does not react as quickly as it should and it needs to be replaced. nox is oxides of nitrogen, a product of too lean combustion which causes cylinder temps to go too high. it sounds like replacing O2 sensor will make it happy. engine computer is having a hard time controlling lean/ rich fuel mix because sensor is slow to register changes, needs to have response time in milliseconds or engine computer can't operate properly. O2 sensors do wear out, normal service item. hope that helps

true the EGR can really make a change and it should have been the first thing too look at because its the cheapest and easy to install
