i would suspect your cat too. do they drive them on a dyno at 15 and 25 mph when they test them? here in california they drive them and if your cat is bad youll fail on nox for sure. it is a 3 way cat but infortunately you dont have egr which helps on nox a lot.here in california the standards are constantly changing to keep a fail rate of 10% of all cars tested. seems kinda bogus, if your running really lean even with a new cat you still might fail so check your air mass meter it should be running with the o2 sensor disconnected about .6 or .8% co.
