Plugs should not have caused this fault message. The code means that Knock Sensor #1 Circuit Knock sensor signal above or below minimum acceptable threshold voltage. This means an open circuit, short circuit or a bad sensor. Since it only appears on tough roads, i would start checking the wiring and connectors, especially if there is not a wire shaved through and making contact with a metal part.
