if one side is lifting you can try adjusting the hood latch on the car to see if its lining up with the latch on the hood if its not perfect it can sometimes make the hood tilt one way when closed. also try adjusting (up or down) the rubber "cushion" on the left and right on the radiator support.
mine use to be like that it was moving up and down. i found out it was the hangar part that attaches to the car. the cf hood latch diameter is too thin. i had to wrap some duck tape to it to make it stop bouncing up and down
