HC, CO passed
NO X failed at 2325 ppm, 1200 = passing

I did not think the O2 sensor was bad...I still think its the Catalytic...

Timing is computer controlled by the ECU so I dont think I can retard it that easily

No EGR on this car

Other causes for high NOX are:
1 Low fuel pressure
2 Dirt Cylinder Head with carbon deposits
3 Hi Op Temperature
