What is the reason why Chang 'an Yuexiang manual gear can't accelerate and step on the gas pedal?

According to your situation, the reason may be:

1, poor oil quality

When there are too many impurities or too much water in the fuel, it will naturally lead to insufficient power, while inferior fuel will easily lead to the blockage of the filter screen, gasoline filter and nozzle of the oil pump, resulting in small holes or filtration, which will lead to poor oil supply and decreased engine function.

2. The problem of carbon deposition is serious.

Too much carbon deposition in the throttle and intake pipe leads to insufficient intake air, gasoline can't be fully burned, and power can't keep up naturally. In addition, it will increase fuel consumption to a certain extent, and the nozzle will be blocked, resulting in poor fuel atomization effect, or no fuel injection at all, resulting in cylinder shortage and reduced engine output power.

3. Ignition coil failure

Ignition coil is damaged, one cylinder can't ignite and work normally, lack of cylinder power is insufficient, and the engine shakes. If the ignition coil is damaged, it should be replaced in time.

The gasoline filter is too dirty.

If the gasoline filter is not replaced for a long time, the gasoline filter will be unclean. If it is serious, it will block the gasoline filter. A common phenomenon is that cars are easy to stall and often fail to catch fire.

5, gasoline pump failure

The damage and abnormal operation of the oil pump will lead to insufficient oil pumping, which will eventually lead to insufficient oil injection of the engine, and the output power of the engine will decrease, thus resulting in insufficient power of the automobile.

6. Three-way catalytic plugging

The common phenomenon of three-way catalysis is that the engine fault light is on, and the engine ring is heard only when the throttle is pressed to the end, and the vehicle speed is slow.
