Car sputter stall in heavy rain

[Charizard]

HELP!
No one seems to known the cause of my problem.

My ep3 sputters and stalls when it rains heavily. You can feel the vibrations through the exhaust.

All stock , lowKs, engine bay is all dry when checking after driving in rain

Any Clue ?

Will it start up again after stalling

[Charizard]

Yes starts up again fine. Only stalls in very heavy rain otherwise it just continues to sputter. No issue in dry conditions.

User error.
















Personally I'm not 100% on the rain being a factor but rather more a coincidence.
how is your fuel economy?

About 450-500 klms a tank. It only happens in rain and vibration felt through entire exhaust. Rumbles under my seat

Obviously engine isn't all good if you can't drive in the rain.. Also didn't you say it was all stock? What exhaust do you have

Maybe.. Dosnt explain the rain factor though.. TBH I think it's gonna be a vac or God aweful exhaust leak still don't know how te rain factors in though... Maybe a crack that's closed due to heat in the dry but the cool of the water keeps it open... Really need more info
