Jetta got off the bus, and the exhaust pipe still smelled of gasoline. What happened when the car was still shaking?

This is normal. At the beginning, there will be more fuel injection than usual, and it is easier to hit the car. There must be some gasoline that is not completely burned, which leads to gasoline smell, engine jitter and high dynamic speed. Water comes out of the exhaust pipe because there are many additives in gasoline to reduce environmental pollution, which will produce water after combustion. When you turn off the engine, the water in the exhaust pipe can't be completely removed, so some of it stays in the exhaust pipe, and when you take a taxi again, you will spray the rest of the water out.
