Here's a link to my thread with very similar issues. I ended up replacing both catalytic converters (california model), fuel filter, both o2 sensors, and thermostat.
I have one cat which was replaced in 08 or 09 by a shop. Fuel filter could a replacement i did replace it once few years ago. o2 sensors are stock which the one behind the cat i will have to replace soon cause of the wire. The thermostat was replaced (stupid location if you ask me) probably 2 years ago. Also thermostat degrees at autozone are all 180's. Will check it out and see what a shop says. Any info on good shops will be helpful.

After all that work finally passing emissions. Failed 3 times and passed today. NOx is 1.4910. I had to redo the intake system, replace catalytic converter, replace spark plugs with NGK V-Power, fuel filter, run seafoam through the intake, gas, and oil, oil and filter change...I think that's all could be more. Did good all the way to my camping spot the other day so should be good.
