    Hi this is Owen.
    Failed NCT for high lamda 1.04 at high idle all other gases OK at co 0.02 hc 027 co2 15.32 o2 0.5 , checked exhaust and fixed leak in rear box,
    re tested and lamda down to 1.02 which is limit for test as it was so close to limit I checked
    further and checked for codes two p codes rich to lean threshold exceeded tried to clear and was given message on scan tool that further driving would be required to clear fully all OK so far, thinking I might speed up the process I removed the 3 amp fuse to clear the kam, started car and co has gone through the roof at 8% and hc 500 and exhaust is smokey will this need a drive cycle to correct this ,
    I would be grateful for any advise .
    Regards Owen
