Lexus Repair: 93 ES300, educated guess, water vapor

Question
When my car is running, you can see smell and see gas spraying out the exhaust. What could be causing this to happen? Please help

Answer
IT MAY NOT BE FUEL, BUT WATER VAPOR, AND THE SMELL IS THAT OF THE ENGINE RUNNING RICH. THERE IS NOT ENOUGH INFO FOR ME TO COMPLETELY FORWARD A GOOD EDUCATED GUESS WITHOUT SEEING THIS CONCERN FOR MY SELF.YOU SHOULD TAKE IT TO A REPAIR SHOP AND HAVE IT LOOKED AT.
