Strange (FACTORY) Holes in Trunk Lid

Cudascott, You're making a little sense. My car does seem to run a little rich. But, even if it wasn't running rich exhaust fumes (non-rich fumes) would still be sucked into the car. When I got the car it had a real strong smell of exhaust when I would drive around. Once I found that my trunk seal wasn't sealing completely I installed a newer soft seal on the trunk lid (as you can see in the pics). My car already had a new trunk seal on the body. Anyway, even with the new seal on the lid I can just barely smell exhaust now. So I know that some exhaust is still seeping into the car. I'll take some pics tomorrow so everyone can see the holes from the inside of the trunk, the inner trunk lid and the trunk are wide open on the inside. The car has no coating (at all) in the trunk lid, it's still bare metal, nice and clean with just a hint of minor surface rust (very, very minor). I know that when a car goes down the road the pressure inside the car drops and if you have any type of exhaust leak near a hole or crack in the body the low pressure inside the car will suck the exhaust into the cabin area. This usually happens when you have a leak under the car but I have all new exhaust and have had it checked for leaks by experts (it's sealed up tight). But at the rear bumper there are the dual exhaust pipes where there is definitely tons of exhaust. When you guys (and girls) see the pics from the inside of the trunk you'll understand why it makes no sense. I can understand the factory putting weep hole in the trunk to keep it from rusting but those same holes also allow fumes to enter the car (if your exhaust comes out at the rear bumper).

not as puzzled now,
