Hey guys, lately I've been smelling a terrible smell coming from my car randomly when i drive. Smells like a vacuum bag set on fire. And there's no set time it happens, last week i was driving to work and it started smelling bad, i thought it was a car in front of me but it wasn't. Then a week later i smell it again. The smell started again today so i quickly pulled over and popped the hood and there was no smell coming from the engine area. This is really confusing any ideas?
