Having a problem passing ny state emissions because of high nox numbers which
read 2.39 exceeding the 2.00 limit. The car is operating normally , no
changes in gas mileage etc. Last year had same problem and replaced the cat,the 02 sensor was replaced 2 years ago. I have no check engine lights
and the car is regularly maintained by me. It has just hit 232 K. Anyone
with some help or suggestions would be appreciated . Joe
