So ever since last fall, my car has been doing this wierd thing where it sputters & dies randomly whenever it's rainy, cold, or has just rained. It did it today as I was going to work. I start it with no problems, it revs up, then the RPMs drop to about 400-500, then it just sputters & dies. if I start it back up & rev it a few times, the RPMs go back to normal & it runs just fine. This ONLY happens in moist or cold weather. Anyone have any ideas? My coworker seems to think it's a sensor issue. It's still under the dealer warranty & I've taken it in several times just for this issue but they can never replicate the problem or find anything wrong.

Oh- and one more question that I'll get out of the way here so I don't hafta make another thread- my rear passenger door fills up with water whenever it rains. I cannot find any place where the water could be getting in other than the drain holes on the underside of the door, but the other door has the same holes & it doesn't leak at all. Has anyone had this problem? How did you fix it?

 

how do the seals and gaskets look on the window? make sure the drain holes on bottom of door are clean. as for the not running, sounds like moisture is getting into a sensor maybe.

 

Everything looks fine as far as I can tell, I have no idea how the water is getting in.

 

Maybe your coil packs are cracked allowing water to get in? When your car dies check your engine for spark perhaps??
