We had a lot of rain one night this weekend and I was forced to go to shopping center for an urgent need. I rarely saw as rain as this time. At some places on highway, I rolled on 2 inches of water at 50 mph. Some minutes later on a red light, the rpm goes very low reaching 200-300 rpms and menacing of stalling what I didn't really want this in the middle of the road, at night and moreover in heavy rain... I put the floorshifter into "P" and the rpm gone to 700-800. Since I bought the car, it never see as much water. I'm wondering if it can be an electric trouble or the engine just "eat" to much water into the intake ? As the car seems normal in the next days, I judge then it's not a emergency troubleshot but thanks for the info.
