96 850t runs fine. P0422 popped up a couple of weeks ago, cleared it. Returned today accompanied by P0326. No detected performance problems. Remind me where to look first? Thanks.

Clean the connector to the Knock sensors and check the wiring for shorts and opens.

Possibly. P0422 is Catalytic Converter emissions efficiency just about anything that messes with the burn process can trip a P0422. If the knock sensor is not working for any reason. The ECM will not retard the ignition if the engine knocks.
