The check engine light on my 1998 6 cyl SOHC Sport came on the other day. I had it read at the local parts store and the error was PO430 catalyst system efficiency below threshold. Checking the Haynes manual and searching the internet I cannot find the location of the bad O2. I understand that bank 2 is on the discharge side of the converter but what side is the O2 on. Any help would be appreciated.
Many thanks in advance.
