Catalyst emissions

with a non functional cat lambda will generally(but not always)be at the high end of the spectrum not the low end.your readings would make me guess at faulty o2 sensor or the wiring to it.certainly running rich for some reason,1.2% co?shud be lower than that with the bloody cat completely missing!loadsa possibilitys from fooked pi$$flaps if twinport to faulty ecu and everything in between.check for oil wicking into the o2 sensor multiplug and fooking up the signal first tho

That's what I thought looking at the scanner live data too.
