What is the reason for the recent decline in automobile power?

1, throttle failure. When stepping on the accelerator, the accelerator cannot be fully opened, which leads to the weakening of vehicle power, so it is necessary to adjust the accelerator cable or pedal.

2. Air inlet failure. The air intake system is blocked or leaked, which will affect the power of the engine. Check whether the air filter, air inlet pipe and various vacuum hoses are blocked or leaked, and carry out maintenance.

The cable is loose. After long-term use, the steel wire rope of the accelerator will gradually loosen, weakening the power of the vehicle. It can be solved by readjusting the adjusting nut of the throttle cable to tighten the cable.

4. The filter element has not been replaced. If the air filter is not replaced for a long time, the impurities trapped by the air filter will slowly deposit on the surface, which will affect the power of the vehicle. Just replace the air filter.

5. The catalyst is blocked. During the long-term use of the three-way catalytic converter, the power is weakened due to carbon deposition, so it is necessary to clean the three-way catalytic converter.

6. Eliminate syllable damage. Exhaust syllable will increase exhaust resistance and engine exhaust reflux. After the damage, the strength will be weakened and the syllables need to be replaced.

7. The pressure is abnormal. The pressure in the fuel system is too low, which leads to the mixture being too lean and the engine power decreasing. It is necessary to adjust the pressure in the fuel system in time.

8, injector failure. The diameter of fuel injector changes due to carbon blockage or wear, which leads to the decrease of fuel injection and insufficient power. At this point, it is necessary to clean up the carbon deposit or replace the fuel injector.

9. Fuel problem. Poor fuel quality leads to insufficient power and needs to be replaced with better fuel.

10, ignition failed. It may be that there is a problem with the spark plug that leads to the ignition failure, so the power is insufficient and a new spark plug needs to be replaced.
