What are the reasons for a car suddenly losing power when accelerating?

[LoganRose]

There are several reasons why a car may suddenly lose power when accelerating: 1. Excessive carbon deposits in the engine can cause the combustion chamber temperature to rise too high, disrupting normal engine operation; 2. Blockages in the fuel system can lead to insufficient fuel supply; 3. Air entering the fuel line can make the air-fuel mixture too lean. The methods to check for sudden loss of power when accelerating are: 1. Inspect whether the fuel pump in the tank is working properly, as a malfunctioning fuel pump can result in insufficient vehicle power; 2. Check the fuel filter for leaks or blockages; 3. Examine the intake pipe for any dirt blockages; 4. Verify if the valve timing is correct; 5. Check whether the intake and exhaust pipes are tightly sealed.
