First of all, do you have a catalytic converter on you car? and if yes, does it work properly? |

Serviced last week new air filter oil filter new oil iridum plugs ... I put in a new cat last week low idle passed with it in at .45 co but high idle was still a fail at .77 co bc ppm was 88 I think which is a pass as well as below 200ppm |

I bought the lamba sensor of a dude on adverts who claimed it was new looked ok had a scratch or two but put that down to anything really maybe it is dodgy as well but would I pass 4 lamba readings with a dodgy sensor ? |

Have you tried using fuel additives? Also heard if you fill your cat with something (kerosene, methalated spirits etc) it brings it right down temporarliy. Do a bit of research to find out what is used. I know a lad who got his evo through by doing so |
