What is the reason why JAC can't step on the gas?

The poor quality of automobile oil will also affect the service life of three-way catalytic converter in exhaust system. If the three-way catalytic converter is blocked, it will directly affect the acceleration performance of the vehicle, and at the same time, it will also lead to the increase of fuel consumption and the phenomenon of weak acceleration. It is suggested to refuel cars at regular gas stations in China to ensure that the oil products meet the fuel standards of cars and avoid refueling at informal gas stations.

When refueling is weak, we must first judge whether the air intake system is in good condition. If it is in good condition, consider whether the air intake system needs cleaning. Remove the air filter and blow off the dust. If it is difficult to blow off, it should be replaced. Check whether the throttle valve is clean, further check the intake valve and intake manifold, and clean it properly if necessary.

Solution:

1. Whether the idle motor, throttle and fuel injector are too dirty, stuck or blocked and need to be cleaned.

2. Check the ignition coil, high-voltage line and spark plug for leakage, aging and ablation, resulting in weak ignition and lack of cylinder.

3. Check whether the signals of water temperature sensor and air flow sensor are inaccurate and whether the air flowmeter can be cleaned.

4. Check whether there is serious carbon deposit from the intake pipe to the valve, and clean it if necessary.

5. Check whether the gasoline pump pressure is normal.
