My 1995 Nissan pick up truck failed the emission test from NOx oxides of nitrogen. The standard is 3.00 mine was 3.26, what could be the problem, is it the EGR valve?

NOX is formed from high pressure and temperature above 2500 degrees. The job of the egr is to recirculate exaust back into the cylinder to give it a cooler charge (exhaust wont burn). Make sure your cooling system is up to par and clean your egr with some carb cleaner and make sure the passages are clear. egr valves and passages get very dirty

I took my daughters 1995 Nissan Altima for its two year smog inspection and it failed three times due to nox failure at levels around 1400. Back in march of 2009 I took it to a reputable shop and they...

Check the ports if there is any carbon,I doubt it,
but you got to look
I would make sure you don't have overheating issues
That is the cause of NOX (High Combustion Temp)
Check fuel pressure
Use synthetic oil in engine
Check PCV Hoses etc
