I have a small gap where the hood close on the driver side. When I shut the hood the left side closes all the way but the right side pops up, just a tiny bit, but anuf that you can tell by looking at the front end of the car.When I press the right side down the left pops up,but it doesn't stay up it goes back down. What exactly could it be. I have noticed other Z with the same problem. You think it could be the hinges.
