Hello,

Im facing some errors with my 2.0 xsi 16V engine. Sometimes i get "catalytic converter fault" and then engine begins to act strange with a big loss of power.
What i want to do is to remove the catalytic converter and insert a resonator (because its much cheaper).
The problem is that there are 2 lambdas, one in front and other in the back of the "cat".
Will the replacement somehow affect the engine's job? Or what are your suggestions. Because i believe that my "cat" is simply jammed. Also i have read that this would improve my exhaust work and its better for engine.

Thanks for advices.:)

If it's not there - the flow of air through the engine will be better - and you'll be belching out a load more toxins into the environment.

The loss of power is the engine shutting down to prevent possible damage - but working enough to get you home - this is normal.

I'd take it on the chin and keep the converter.

Peugeots are notorious for throwing up faults that have nothing to do with the description - so you're 'catalytic converter fault' could just be a dodgy sensor.

As all kit, oxygen sensors have a limited life span - but they are cheap to replace - so I'd change the sensors. If no improvement - you've ruled them out and saved yourself having to replace them in the future.

Seems to be a push to get rid of polluting cars on the road - wouldn't be at all surprised if the tolerance in mot tests gets smaller -so keep the converter.

Many thanks for explanation, will try to change those o2 sensors, but in my country in EU they are not so cheap, cost about 50 euros for 1 piece.
