For the past one or two days, there has been a rotten skunk smell in my car. While I was driving I passed a skunk which I'm assuming was just recently killed. The skunk smell from my car was only there for a few minutes, but I noticed this morning when I got into my car to start it, it smelled like skunk. The car hadn't even been running. Same thing this afternoon when I got into it. I don't know how that happened, or what to do?
