Emissions problem on my audi.

[monsterhunter]

Well guys, i have been constitly(SP?) failing emission while im trying to get this car to pass inspection. its the only thing im failing and i need some help here. i just bought a new cat, but i put it all the way back where the tailpipe should be. the HCs went down almost to passing but the COS went way up.my main question is; Since the cat is that far away from the motor is that whats causing the COS to go up? Or is there something else wrong? The car is a 1992 audi 100 quattro 2.8L with 187k on it. any question to help out just ask. and il try my best to answer it.



Thanks in advance Jay.
