I may have steered you in the wrong direction with that suggestion (O2 sensors). I was thinking of the O2 sensor locations on one of my other vehicles when that thought occured, but now that I've looked up the O2 sensor locations on a VX, I doubt that a high-pressure wash in the engine bay would have brought much water into contact with the O2 sensors. They're located more on the underside of the vehicle.

If I've interpreted the CD manual correctly, the cylinder misfire codes are based on crankshaft-position sensor (CPS - abbreviation) readings. These codes will be produced if the engine isn't running smoothly, which just causes the CPS to not be in the position it would/should normally be in when the readings are taken. In my opinion, that doesn't really narrow it down much though, because there are a few different things that can cause the engine to run rough in the first place.

I know the subject of spark plugs has been brought up. Have they been checked visually for cracks in the insulators, or possibly water in the spark plug wells? Those could cause misfires.

It may also be worthwhile to disconnect the crankshaft position sensor and apply some dielectric grease to the connector.
