Failed on C.O. and thinking it's the single Catalytic Converter, is that right ?

I had a sierra sapphire 2.0ltr DOHC years ago took, it for a rolling road tune and my emissions was high every time they adjusted it and rolled it again emissions went high turnt out to be the potent meter which controls mixture, it was bolted on drivers side inner wing if this is of any help

The way the reading dropped on the second fast idle test would make me wonder how hot the cat was?

Before spending on a new cat; get the oxygen sensor reading checked and the in and out temperatures of the cat - should be 50C hotter coming out.

Mmm...I should've said had a Head Gasket leaks few days ago, althought it is now sorted and I'm wondering if the old Coolant have killed the Catalytic Converter off or even made a mess on the Hego Sensors reading even so it's passed on them ?

lol! what I have heard if a parked vehicle fitted with Catalytic Converter(s) has been caught out in a heavy rain storm where some flood is likey to happen, it will damage the C/C straight off because it's placed underneath the vehicle where the rain water can get into the Exhaust pipe(s).

Utter tosh; the only way that a flood can damage a cat is if you drive through deep water and the thermal shock of the red-hot cat contacting the water causes it to shatter.

Even that is almost unknown.

However; a head gasket weeping anti-freeze into the cylinders can damage both the cat and the oxygen sensor.
