Did you find out whats wrong here? It happened to me today. I was on my way to the doc's and hit a huge puddle in the middle of my lane at 35mph (the kind that makes a loud noise and brings your car to an almost complete stop) ... as soon as that happened, my car BOGGED right down and the SES light began to flash. So I pulled over to the side of the road, turned the car off for 2 minutes... I start it up and it seemed fine... then immediately when I started going up a hill, the light started flashing again and bogged right down... I eventually had to manually put the car in 1st gear to get it up the hill. I let the car sit for about 15 minutes running and sitting before I went on my way... the light hasnt flashed for about 30 minutes, but I still feel a little loss of power.
