I�ll be driving under normal conditions (Not fast or racing or anything) then when I hit the breaks or use the turn signal or turn on the high beams it�s like there is a surge. All the dash lights come on, throttle doesn�t respond, and it�s almost like the car stalls but it catches itself. It will only last for a couple of seconds at most, and then everything goes back to normal. It happens without warning but from what I can tell happens whenever I use some form of lighting; break lights, turn signals, high beams.
The problem has become more common over the past few days.
Anyone heard of this or know of a cause?
