Cycle problem in rainy weather

206 1.4 Gasoline engine, when the tension belt or bearings get wet in the rainy weather, the idle of the vehicle starts to travel between 1000-2000 rpm.

This situation either resolves spontaneously in a few minutes or if the vehicle changes to normal level over 2000 dd in gear, there is no problem.

The tensioner bearings and belt had changed as a set 20,000km ago.

Again, when heavy rain wasted, he had recovered without stopping or stopping several times, but this is not very common.

I do not think there is such a problem with the belts, the tip of the air cleaner can be watered if the hole in the hood is broken etc. If there is lpg, it can be made when the engine is cold or it may be caused by the idle valve.

I guess that the belt is raising the speed because the belt cannot scrape enough power to the hydraulics, because it does not matter when the engine is cold in LPG when it is hot.

If you are experiencing this kind of event in the rain, no matter whether there is dampness or not, the suspect from the coil or ignition system has told me ...

look at the air filter muffler I think it may have taken water how the car's oil level is normal or more

If I say the ignition system, I think it should be done when the cycle rises, since the original air filter system warned me that it can get water, I had the cheap filters installed in the last months, the filter is close to the hood, it is not a place to take water, but if it took water, does it not show at high speed? The oil is normal, the oils and filters were changed in the summer.

If I have the opportunity, I want to try and drop water on the belts.
