If the engine's running there's less chance of water build up, less chance of it sitting in one place due to heat etc. It can't hurt to have it on anyway, might as well.

cold is better and as said cover main elecs. 
what he said tbh, even a hot engine isnt going to stop water build up just jet wash from a distanace
Fair enough if you get away with that but I'd rather not take the risk in jet washing my sensors and ignition stuff.
And I don't see how is steam worse for electronics than water popey? And why would a bottle of engine degreaser say to keep the engine running while doing it? Do you not think they'd have done a bit of research into whether the engine should be on or off?

I'd say it's the opposite tbh. Like when you're fording deep water, you keep the revs up a bit. I usually turn on the engine as said while rinsing it.
what fording water got to do with washing the engine? The revs have to be kept up to stop water going in the exhaust

I know it's not the best example but imagine you were to get a hose straight into your throttle body. If you were to pour a small amount of water in it, it's going to be more likely to cut out idling rather than sitting about 2k revs isn't it?
