Melted a plug wire - 2006 4.3 130K miles
loom came loose and wire cooked on the exhaust manifold.
replaced the wires, plugs and now I get P0420 - generic code for catalytic converter on bank 1 not meeting minimum standards.
Is it related? Will the fouled convertor burn clean or am I looking at new converter?
Should I go outside and throw rocks at the truck?
