If you do that, make sure you cover the engine with a tarp or something similar so that nothing gets down into the plug holes.... I wouldn't do this unless as a last resort.
You have your way. I have my way. As for the right way, the correct way, and the only way, it does not exist.

It is more likely that you have water on the engine. One or more of the spark plug coils may shorted. On a hot sunny day, open the hood and let the electronics dry out. If possible remove the plastics engine cover to expose the spark plug coils and hopefully your problem will go away. Good luck!

I had to drive to Nashua this morning, 90 miles roundtrip. The car seems a little better, but it still feels strange somehow. At higher RPM, it still clunks.. The first thought I had when I felt this was that my coils had arched.. They did that in the X5 when I was driving, and the feeling was the same. Cruising at about 75, the car will sometimes start making this droning noise. It goes away after a while. If I rest my hand on the shifter at idle, it seems to be shaking more than normal. Even the handling seems a little off, but I could be imagining that. One of the reasons I thought I had water in the engine was that when I was driving home last night, some water dripped onto my foot from somewhere under the dashboard.. I was wearing flip flops, so I felt it. The car starts fine, but it sounds a little strange at first. All the electronics seem to be working fine.

Driving it really is a bad idea until you can get it checked out and letting things dry. Here are the bad things usually associated with water and clunk: cracked head, spun bearings, bent rod, etc. You should at the very least drain the oil and make sure it looks ok.

Change your oil right away !!! For the price of an oil change vrs a new engine, it is a small price to pay for something that might fix your car.

all the other suggestions sound good as well. But, you do not need to remove the park plugs to dry them out, however I would take out the plugs and examine them. I think there is a chart on what a good plug should look like, if not google it.

This is going to sound funny, but I had a GTX that hit a huge puddle, more like a small lake. It was soaked from head to toe. when I chugged all the way home, I changed the oil twice. Changed it once with a crankcase cleaner, then changed the oil again. Enginve was fixed. As far as the water dripping on your foot, I had the same thing in the GTX, (now this will sound funny) but I took the dehumidifier from my basement put it on a board on the front seat and craked the window a few inches. I let it run overnight in the car and in the morning it had almost a full bucket of water in it. The car smelled fine and was perfect to dirve then next day. Never had a problem again.

Good luck, let us know how u make out.
Nobody cares what the definition of “is” is.

I wouldn't bother to change the oil, but I would pull the dipstick and see if the oil was a normal colour. If it is a beige/white colour, you have water in the sump. If not, forget about it.

I don't see the connection between water in the footwell, and water in the engine. Possible, but a real stretch. It is far more likely that if there was a heavy rainfall, or you drove through deep water, that the ignition system is wet. You even noticed the similarity to the coils arcing.

Yes, there could be a bent valve, but that doesn't fix itself, and you note that you can drive at over 4000 rpm. Again, it is possible but unlikely.

Go back to the advice of Tomaz, and make sure it is dry under the hood. Then go to the dealer and get the codes checked. Drama over.

If you have water in the combustion chamber there is only one way it would get there (short of a blown head gasket) and thats via the intake. The odds of enough water getting that far and past the air filter is next to impossible in any normal rain or heavy storm. If by some chance water did get past the air filter, past the MAF without damaging it and then to the composition chamber it would be turned to steam immediately. And you would probably not even notice. If enough water got in the intake to do any more than turn to steam your engine would lock up.
Without a OBD code triggered, you do not have a major problem, and probably not water related.
