Question on BMW 3-Series E36 O2_Sensor

Hi, I have a 316i e36. Only when it rains and I drive on the very first puddle the car starts bogging at low rpm, I have to press the throttle untill 3/4 and then revs up again.
Then you go down at low rpm and bogs again, and again if you put the throttle to the floor revs up without problems.

DME not flooded, fuel pump checked I have LPG and the problem is similar with both fuels
What can I do?
I'm sure it's just something that gets wet from under the car but I dont know what..

You could have water entering the engine through the intake air ducts. Check if the air filter is wet when this happens.
