DOn't know if my situation applies to you (94cs). The car failed NJ inspection a few months ago. High NOx. As high as 1846 if I remember correctly. Replaced the cat converter on second try. No good. Passed only at the third try. Turned out the spark plugs have been eaten away (at 140k miles, original I think. I have never replaced them during the 50k miles I own the car). A new set of properly gapped plugs solved the problem.
Readings of all three tests are in the posts archived.
