Hi, I'm a little confused. With lambda up around 1.1 and a new sensor showing no difference isn't the reason for cat failure due to the continual rich mixture it has to deal with? 3 cats in 2yrs seems to indicate that there is an underlying reason for this. Why does a high value of lambda coupled with a raised co level indicate a failed cat? What were the HC readings? Was the O2 sensor switching correctly?
