Blanca,
I am going to assume your bike ran flawless before the wash. Is that a yes?
I'm going to take that bet. Plugs look good. I thought a sooty plug and that PC messed things up, but that PC is not the problem. So, I assume once again, before the wash, this bike ran crispy and all that good stuff. Is that too, a yes?
I run a fuse on the hot side of the piggy, then I run the hot to the bike. If I have a piggy problem, I remove the fuse, this shuts down the injectors. See, it's kind of simple, Blanca, you are right removing all the injector PC signals off the throttle body. And if your remove the ground thinking you have the PC/piggy disconnected, you forgot the ground resistance in the injector wires you tie into. If you had the hot removed, this removes all the 4 signals and ground is ground. It will not matter now, because there is no resistance at the injector. Therefore, ground is ground, no harm no foul on that end of the wire. But on the on other end of that wire, the PC being in the middle. Here, think a simple resistor from radio shack is one wire on one end, the Pc (resistor) in the middle, the red (wire) is the other side of the Pc box. Forget the injector wires for now.
Can you see what will happen with the combination of the 2 differences of removing either wire off the Pc? Setting up that one fuse for quick diagnosing? This way, you can quickly tell if you have a bad PC or a bad ECU/injector/fuel deliver kind of diagnosis. It gets worse chasing your tail you still have the pig in a resistance mode trying to find a washing incident dripping on your PC box.
I find that a kitchen product, Glad brand Press'n'Seal, can cover parts that you do not want to get wet. The tack on the one side eventually will stick to the surface of the part. I'm warning anyone if you cover a paint job, leave it for months in the sun kind of warning? The nice part is that gas does not eat at it, nor oil. It's microwaveable, so it can take the bike's heat like the other plastic parts do. Cover PC that now that is exposed to water. When you wash the bike again, see if the next time you did not get water in the diagnostic scenario.
So, did the water not act as a resistor on the outside shield of the PC unit? If you think radio wave, you stumble over that water as the wave kind of spikes over the water drops, you get that spike like if you run a digital camera close to the bike's telemetry, you hear that spike and then see blocks of the old video you are copying over come into view as the noise reference is what I think it is.
So, I would not chase a thing if you said yes to the two questions above. It's the water... Is my guess.
