2002 Kia Optima 6 cyl Four Wheel Drive Automatic 121000 miles
when driving the car, the car will try to stall. If the lights are on when applying the brakes the lights flicker, the radio will shut off, the panel on the dash fllicker. Have replaced the alternator, the switch that dims and turns bright light, also had baterry tested, had a a test run, it said low drain, but not where it was coming from. The car has knocked off when I was driving it. After a few minutes it started back up.
