Check the adjustement of the two rubber stops behind your headlights, too. The hood should be firmly pushed against them. Get some play-doh (no kidding) and a little vegetable oil or Pam spray. Put a little on a paper towel, then rub it on the rubber stops and the pockets in the hood. This keeps the playdoh from sticking.
Now make a small ball of playdoh, about the diameter of a marble. Place a piece on each rubber stop, and GENTLY close the hood until it latches. This will tell you if you have a gap or not. Check the thickness of the playdoh to determine how much to adjust. Repeat as necessary.
