Hi Nigel, Colourful use of descriptions for "rev at high speed" and "poor quality cat". Colin, As both Nigel and Tony say those gas readings clearly show the cat is doing nothing. The fact that the emissions are near perfect for a car not fitted with a cat (in closed loop) and the fact that you say the O2 sensor is working ok (in closed loop), suggest to me that either the cat is not warm enough or you have used a cheap poor quality aftermarket cat on it. HTH Mike
