Update: I was still unable to source the issue, so I finally took it to my repair shop Certified Auto in Fort Myers. They didn't get the 2 codes I was getting, P2096 and P2099, but instead got 4 Oxygen sensor codes. I told them I never cleared the codes since I last read them and to re-read the codes with my Mac Tools tool which I keep in the car. They did get those again, but said they are generic codes. They did a smoke test after that and found that thete is a leak where the vacuum tube goes from the brake booster to the intake. It doesn't appear that this is a serviceable part, so they recommend replacing the intake. Stealership price for an intake is $2300.... lol. They already knew my answer to that. I'm picking it up tomorrow and it'll get a bead of black RTV. Hopefully this will be problem solved. I'll report my findings.
