Hello, 05, 1.8, manual excelle, what is the situation that the engine will shut down suddenly when there is no fuel in normal driving?

There are many reasons, generally because the oil is too poor to reach the corresponding calorific value. The ignition energy is low, the spark plug gap is too large, the ignition coil is aging, the combustion is not good, the water temperature sensor fails, and the EGR valve works badly.

It should be noted that long-term use of inferior fuel will lead to premature aging of the internal spark plug, and the gap between the spark plugs will become larger, which will lead to nozzle damage, thus leading to engine idling and flameout.

Matters needing attention

The typical fault that a car can only be started by stepping on the accelerator is that the battery voltage and starter work normally, but the engine can't be started, so it is difficult to start with a little step on the accelerator. There are also corresponding fault reasons such as accelerator, idle switch, water temperature sensor and temperature sensor. In addition, the quality of fuel used in cars is poor, and the combustion effect in engines is not very good.

For the fault of the accelerator, the voltage between pin 5 and pin 7 of the accelerator control component can be measured (stepping on the accelerator pedal or pulling rope), which should be between 0.4 and 4.5V under normal circumstances; If the voltage is abnormal, repair and replace the throttle potentiometer, repair related lines, and adjust the installation position of the throttle pull rope.
