Having some trouble with my car. Just yesterday on my way home my car started to idle real ruff as if it wanted to die. I made it home and now has this strong gas smell inside and out of car. Tailpipes leaking gas and white puffs of smoke coming out (maybe due to gas). The car is idling as if it was getting flooded with gas. Any ideas on what it could be. All the help will be greatly appreciated. Thanks
