Knock occurs during operation due to premature ignition. Dieseling occurs *after* the ignition is switched off, causing the engine to run on unintentionally.
Common fixes include using higher octane fuel, lowering the idle speed, cleaning carbon deposits from the combustion chamber, or ensuring the throttle linkage isn't sticking.
