I just failed my emmissions test. They said my Nox was too high. I don't know what that means, but does anyone know what I should do?

The guy told me it may be my catylic converter, but I read on a post somewhere that if your converter was bad, it would smell like rotten eggs. My car doesn't smell.

Also, I read that the EGR valve could be the problem. I do have that surge hesitation thing under 3000 rpm, so maybe that could be it? I know you can clean it, but I'm so clueless when it comes to working on cars.

The car passed emissions in New Jersey, I don't understand why it wouldn't pass in California.

Any advice would be great.
