Ummm, I'm a little worried.

Just cruised down to the 24HR Wal-Mart and the inside of my car started to smell like somthing burning. Then my eyes got all watery like smoke was in the cabin. I couldn't tell if there was any. Is my car gonna catch on fire tonight, or am I being paranoid. This wouldn't be the first car to catch on fire in my driveway (98 Explorer)
