Strong smell of gasoline fumes means that there may be other issues involved than the O2 Sensor.
If it is enough of a smell that you believe gasoline is leaking in the engine compartment, I would not drive the car. The catalytic converter goes up to over a thousand degrees under the car after it is stopped. If vapors accumulate in that area. You could have a fire. NOT SAFE !!.
I would have the car towed to the nearest reliable service facility if you suspect a leak.
If you are working on the car yourself. Open the hood, pull the air cleaner and look for leaks in the fuel injection system. Along the fuel rails and where the injectors go into the manifold.
If it is just flooded then that could have something to do with the O2 Sensors. Please, use caution.
Hope this helps,
Mark

Why would I get a gas fumes smell when car is sitting idle or just been shut off. Cannot find any leaks in gas tank or lines


gas is a very high evaporative liquid..fumes extremely strong..if overfull it will smell..and if emissions equipment has issues it will smell also.. when the engine gets hot, any gas present will vent off until the engine cools..thats the fuels evaporative nature..still keep an eye out for issues..

Sounds like a leaky fuel line somewhere and the pressure isn't strong enough to go through the fuel pressure regulator. Try to locate fuel leak by smell.

Strong gas fumes coming from 2001 windstar


The "cause" would be a fuel system or EVAP system leak. If the fumes are that strong, then I would take the vehicle back to Ford again and make the sevice manager stick his nose in it and then tell you there is no problem....

'99 Maxima SE manual with 147k: I had my car parked (on grass) for 2 years while I drove a company vehicle. I just got it back on the road and am getting codes for rear upstream O2 sensor and knock...


O2 sensor is mounted in the exhaust manifold ,

Knock Sensor Strategies: A failure with the knock sensor can cause spark knock and engine damaging detonation because the PCM will not know to ****** ignition timing if knock is occurring.

I suggest to replace spark plugs before you return back.
