Low idling rpm only during the rains

Hi,

I own a 2013 hyundai i20 petrol base variant, it has a very unique problem that I have ever seen to a car. During rainy season, while starting my car the engine starts to go below 900 rpm that is below the idle RPM. The problem occurs only when I touch the accelerator pedal, but the problem goes away after 10 minutes of idling. I have cleaned the throttle body and replaced the air filter during the last service.

The strange thing is that the problem only occurs in rainy season. No such problems in summer season and even if it rains in summer, the issue comes back. I don't have to drive in rain for this problem to occur. Just sitting in my garage is enough for this to occur.

My car has only been driven about 25,000 kms

The fuel efficiency on highway is an approximate 13km/l and 10 in city (is there something that i can do to get more?).

Please help me with the above problems.

Thanks in advance.

This is mostly likely happening due to humidity.

Similar phenomena has been reported by others as well (In other forums), during rains.
