What's wrong with the Bora car not filling the door?

It may be caused by excessive carbon deposition in throttle and idle motor. It is suggested to mainly check whether there is carbon deposit in the throttle valve, and at the same time clean up the carbon deposit in the engine intake and combustion chamber, which can be carried out by hanging bottles. Finally, the diagnostic computer is used to detect whether there is a fault code in the engine and initialize the injection time of the throttle and injector.

Reasons for not being able to refuel the valve:

1. The fuel system is blocked, such as nozzle, gasoline filter or fuel quality.

2. The air intake system is blocked, such as air filter and air flowmeter, which can't fully burn with fuel.

3. The ignition system is not easy to use, such as spark plugs and high-voltage lines.

4. The gas distribution phase is wrong, for example, the intake and exhaust valves are not tightly sealed.

5. It may be the engine oil. If you have recently refueled, and this problem did not exist before refueling, then there is a 70% chance that there is something wrong with the oil at the gas station, which may be mixed with water or other liquids.

6. It may be related to water inflow. If the engine enters water through the air intake, it may cause the air pipe to bend or the piston to be damaged, resulting in insufficient cylinder pressure, so that the car cannot refuel when stepping on the accelerator.

7, long-term maintenance, leading to aging of various systems, so that the car throttle can not add oil.
