po420 error code
So I got the po420 error code. I had one of these a while back - one fixed with a computer flash, the other needed a new Cat and o2 sensor that the dealer replaced under warranty.
I received another one, just today. I imagine that the cat is going, again, along with the o2 sensor. Does anyone know how long these parts are under warranty from Mazda?
Thanks
