Stroll down to your local China/Pakistan supermarket and get this, improves and make it work.

Thank you very much. Such helpful feedback. Cheers

I used to spray Q20 around the rubber seal. Water would not cling to the housing.

The one plug was not working as it should and so, the water did not burn. So, I took all of the out, used a cloth to drain the water, applied and Q20 and replaced with new ones. My problems went away.

The vehicle is a Hyundai Getz, I also thought about the rain. I opened the bonnet, I couldn't see how the water could possible land there.

I had the same problem with my polo 9n3 when it rains. The issue was the front grill had a big open vent which when you look through it, you see the plug leads. So the spray from the cars in front entered through that vent and filled into the plug cavity.
I sold the car. Problem solved.
You could try blocking the vent in the grille if it's the same for you.

That would not be a wise thing to do, it's better to just design something to shield the spark plug holes, messing with airflow is just asking for trouble.

so even a bit of water can make a car idle strangely, especially if its around the spark plug holes,
and yes plugs were recently changed, not sure if I need to change the actual leads as well?

since the Picanto is almost the same as the Getz, only smaller,

maybe that's whats going on here, before I begin to think MAF sensors/fuel type (95/93)
or bad cheese @FiestaST

What year is you picanto? I doubt the engine is a smaller version of the Getz, was it not a 3 cylinder?

Yes, looks like the 1.1l 4 cylinder has the same layout.

Head gasket leaking most probably

Head gasket usually sits way below any spark plug indents

Most cars are fitted with plug leads that seal the plug hole with a rubber seal on the connector to ensure no ingress of water.

Either the seal on the connector has perished and doesn't seal any more or an aftermarket plug lead without a sealing ring is/was used.

I also experienced this problem. Hyundai gets 16v .. but I noticed it after parking my car near a water source. It was not raining. Engine was dry. I parked at parking which had an open flowing drain in front of it .. prior to parking my car was running fine... Start the car and it misses... Go home and check... Alil of water on the spark plug of the 1st cylinder.. btw... Leads are recently replaced (boogie cords used) I used a rag to dry up the moisture... Car still had a slight miss.. but after a few days it cleared up... I guess with engine heat it may have evaporated....

You just parked closed to flowing water and all of sudden the spark plugs are full of water? Seriously now, what sorcery is this?

That's the only source of moisture. And vehicle was fine prior to this. As I said alil water on 1st cylinder sparkplug... Not full of water on spark plugs....
