Have a raw fuel smell every time I park my car
It has happened multiple times over the years that when I press the gas pedal to go, the car does not go or does not accelerate. Several times it has happened when attempting to make a left turn. So the car goes enough to get me in the way of the intersection but not very fast so I have been nervous that I might get hit. Generally stomping the pedal a second time gets it to move, but it is unnerving. I'm including the most recent date this has happened in the next part.
