Need help identifying this smell please

While driving my stock C6, I smell something that almost smells like propane. It may be only when the A/C is on, but not 100% sure. Anyone have any ideas what to check?

The HVAC system can emit some nasty funky mildew odor that's worst at start-up.

Certain batches of gasoline can have high sulfur content that makes for rotten egg smelling exhaust.

Plastic bags stuck to the cats will smell bad too.

My car has a faint odor when at idle and it smells like that orange coolant smell when you take the cap off. I have zero leaks, and the car does not run hot.
