Just got the P0422 code V70-XC70 2000

P0422 = Main Catalyst Below Threshold (Bank 1)

The front O2 sensor has a problem. NOT the cat! Cats cannot be rebuilt. You could spend a lot of money putting on a new cat with O2 sensors, or you could just send me the cash :) I could always use an extra grand!

Before you spend mega bucks, you need to determine if it is indeed the O2 sensor gone bad (which I doubt) or one of the many vacuum hoses that is leaking and allowing outside air to enter the system. Also, when was the last time you had a tune up? Plugs do make a difference in how much fuel is being burned.
