    Default 2008 Silverado 2500 Cat problem

    I have a 2008, Silverado, 25000 miles. Everytime I drive it in slush, no snow, not wet roads, the check engine light comes on and according to the dealer, the catalytic converter needed to be replaced. This has happened 4 times now. Yesterday barely made it home. Truck lost almost all power. Now I am being told there is a problem with the 02 sensor. Scan test found P0300 also p0430 for bank 2.
