Is My Cuda Killing Me?
Go to ace hardware, buy all the plugs for about $3 and put them in yourself. Don't pay a shop to do it.
2 big plugs go under the spare tire.
But like was mentioned….. The missing plugs could only be part of the problem.
Could also be all the holes in your trunk lid…… This thread.

Put some tape on the back side of all those holes.
