    Hi check the ground connections, check the fusebox and wiring, also you can reset the
    red lightning bolt on your dash, here it is, put on ignition and wait until most lights turn
    off only engine light stay on, slowly push accelerator pedal to the floor and release it
    also slowly, turn off ignition. after this start the car and see if all the lights turn off and
    car runs normal.
