I think I found the problem. I don't know why I never noticed this before. See pics above. I think this gray vent on the outside connects to the ducts inside the house. I posted pics to show but the vent in the house (kitchen) is directly behind the vent outside. And it looks like the vent outside isn't flush with the wall. And this is where I feel most of the air coming in and it's a lot colder in the kitchen. I hope this is it. I think it is. Regardless, I want to thank you guys for your time and help. I will still post what I find out from the energy audit tomorrow.
