I was driving my wife's car a 2005 ford focus(automatic) ran into some water not sure how deep the water was on the car by the time i got out it had already receded. anyway the car stalls and will not stop. i pushed the car into a parking lot and it has been sitting there for about 4 hours. when i put the key in the ignition everything is fine when i turn it to the next position all the lights flicker, fade, go off, then come on like everything is working perfectly. when i try to start it the lights fade and flicker and sometimes you can hear a faint humming sound. any ideas? tomorrow i am going to check air intake/plugs to see if it sucked up water..
