[DML] Re: Maybe Catalytic?

I would still suggest you make sure the mechanical and vacuum advance
are both working. Just checking base timing would get you to pass at
idle but at speed, if the advances are not working correctly, you
would fail. You could still have a bad pattern on an injector too. The
combustion chambers could also be carboned up causing high combustion
temps and high NOX. It is not common for a CC to go bad but maybe
someone hollowed it out or overheated it with a too rich mixture.
