jack it up and look underneith it. more than likely you hit something and popped out one of the screw fasteners that holds it on. look behind the sideskirt where it is attached to the car by about 15-20 plastic screw fasteners. there is also one underneith the jacking access slots and one on the front and rear of the side skirt
