Message	HC's are generally from a rich condition. CO's are often exhaust restrictions NOX is generated from hot combustion temps. Make sure those O2's are in good shape. Make sure the engine is warm, but coolant system is performing correctly. No restrictions. UD pully without HI water pully.. EGR? I know the car can pass without it, but it goes both ways. Cats in good shape? Not plugged up?
