Hyundai Lang Lang turns off the engine and drives again, which feels like flooding the tank.

Hyundai Langlang has the feeling of flooding the cylinder after turning off the engine, and the solution is as follows.

1. At this time, the throttle position sensor sends a special starting condition signal to the ecu, and the ecu activates the overflow clearance function according to the internal settings. The fuel injector automatically controls to interrupt fuel injection for about 3 ~ 5 seconds, at which time the throttle valve is fully opened and the air volume is the maximum. So that the gasoline vapor in the cylinder is removed, the spark plug is quickly dried, and an electric spark is generated between the electrodes of the spark plug. At the same time, ecu automatically controls the fuel injector to resume the fuel injection procedure, and the engine stops immediately. At this time, the accelerator pedal should be released quickly to avoid the new fault of "cylinder pulling" caused by high-speed operation of cold car.

2. If it doesn't work, remove the spark plug and repeat the last action for 3-5 seconds, 2-3 times.
