Re: Millenia S 1999 P0431 code

Sometimes the valve cover gaskets will leak around the the spark plug area and let oil in there, giving an oil smell and also causing a misfire which could damage the converters. The precats are built into the maniflods on millenia's. They give a rooten egg smell off if theres too much raw fuel entering them..... was there any other codes?
