While driving sum slight hesitation after shifting-when coming to a stop if I apply the brake or turn on blinker radio will turn off then back on. When I start the car I have to make sure the radio turns on before it will start even then sometimes I have to keep messing around w/ it to start. When it's rolled over there is nothing no clicking all lights are on though. Also interior as well as headlights flicker only when you shift. Any ideas?
