Hi guys, I have had a Toyota avensis 2.0 on a Y plate in which has done lots of miles, I failed it on high lambda and a severe blow around the catalyst, We replaced the catalyst the following day and the lambda is now fine but it is now quite high on CO. Any clues as Im Guessing it is to do with the cat? It does also have a coolant leak and is showing possible signs of ahead gasket issue. Of course the boss only cares about not being able to charge for the cat if it wont pass the emissions. Any clues guys?

As a worker in a responsible skilled roll within a skilled trade why am I paid so poor??

What are the gas readings? The high mileage ones are a real pain to get through.have you done a test on the head gasket? Have you got a scanner? Injector durations? High mileage ones are prone for injectors leaking back in turn burning the cat out.so lots to think about, if the head gasket is ok most people don't want the expense and just fit a after market cat

It was only run aroud a village and when on airport runs it was low speeds.

Like Daddyb said give it a good roasting and it should sail through.

The CO readings were hovering around the 0.60 mark so not massively high. Thanks guys.
