normally i would replace

***********1. o2 sensor........major source of fuel trim info

2. intake manifold gasket.....vacuum leak inducing to much air so it runs lean causing higher nitric oxide levels

this where i would start

air mass meter not likely
coolant.... seriously?
cat converter has nothing to do with high nox. your nox level is so high the source is the incorrect setting of fuel trim (o2 sensor) or actual combustion (too much unmetered air

does your car have egr? unless its from california not likely
