I recently had the same problem. It turned out that the fuel regulator on the engine at the left side just above the intake manifold had an intermitent leak. The gas leaking was not always visible so I had the regulator changed and that solved the problem.

Why is a very strong gas smell coming from my tailpipe?


White smoke is water vapor and in this cold climate it is normal. Strong gas smell is not normal although you may smell some while engine is warming up. Bad cat converter can produce smells, but usually more like rotten eggs. If engine is running rough and seems rich, check coolant temp sensor. Bad converter can cause stalling too. Otherwise, idle speed is controlled by idle air contol motor which can get dirty and stick. Any codes set?

No service engine light? A loose gas cap will set a light.
You may want to inspect your fuel filler neck and anything close. For a long while its not uncommon for a person to report the fuel odor issue and have it be where some low life cut a filler neck or puntured a tank to steal fuel. But if that were the case there would usually be a service engine or gas cap light as the systems now days monitor pressures so they can detect leaks in the Evap system.

When you mention a smell though under the hood, do you think the smell could be exhaust? I have seen those manifolds crack. or maybe just a leak from a gasket or exhaust donut.

Strong gas smell and poor gas mileage


If the gas odor is coming from the engine, than the problem is most likely a cracked or poorly seated fuel injector.

Strong odor of gasoline vapors


do u have a check engine light on? do u overfill the tank? which is to say when the filler nozzle clicks off do u still try to put more fuel in? in any event u most likely have a overloaded carbon canister, pull the canister out and check it for gasoline saturation, the carbon canister is located under the car in a tray near the fuel tank.
