Hello all! I am brand new to the site & being a Land Rover owner as well. Bought a 1997 Discovery for a song but with some issues. The Catalytic Converter is bad and the check engine light remains "on." My state does not require any inspection or emission standard. If I were to ream out the converter, how can I get the check engine light to remain off? I would like it operative for other problems which may arise. Thanks
