SOURCE: failed smog test
trade it in on the scrappage scheme against a new one .or take it to an authorised garage for emmisions ,cant just point a finger at a certain component and say change that .Sorry but without the right equipment i would only be making educated guesses .What condition is the air filter in ---did you clean it before you went for the test

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

There are a few ways you can do this:
Use ultra-low sulphur fuel (not sure if the US has this but the UK does).
Change or clean out the air filter (check my profile for a how-to)
Make sure the EGR valve is connected up properly. This is the exhaust gas recirculating valve, located on the intake manifold. Unbolt is, clean it out with a wire brush and carb cleaner, refit.
Get the Nissan checked again, if it is still high, the catalytic converter could be due a change, especially as it will be 12 years old.
Hope this helps, please vote if so. Thanks :)
