looking at an 01 v70xc

Unmetered air in the intake causes the ECU to enrich the mixture which then coats the plugs with too much gasoline and the resulting bad burn coats the O2 sensors.

Over on Volvospeed, or was it the UK Volvo site, someone demonstrated how to clean off an O2 sensor with a blowtorch. They cannot be cleaned by rubbing with anything, rubbing destroys them. So, I suggest running it hot after finding the cause of the rich burn. If it works, it saves a few hundred bucks.
