On my Furio, I have a fault that pops up every few weeks. Never affects engine performance.
Got a cheapy chinese reader/eraser with code book.
Always same code and is something like, CAT, bank 3.
My CAT is the upright engine type, that the down pipes go into.
Guess its 3 of 4 on something but not sure what it really means?
Is there a sensor for the 4 down pipes that measure gases before entering the CAT? I've only noticed the sensor below the CAT towards front exhaust section.

AND would you attempt to change the CAT sparkplug on an old CAT. I tried loosening it and it won't budge!

Thanks.
