What causes the EPC warning light to come on and the throttle to feel weak?

[MariaRose]

EPC light on and lack of power when accelerating can be caused by the following reasons: 1. Fuel system issues: The fuel system is a common problem area in cars. Insufficient fuel entering the combustion chamber may be due to clogged fuel injectors, fuel line leaks, reduced fuel pump performance, or a blocked fuel filter. 2. Blocked fuel filter: The main reason for this feeling of powerlessness is the engine suddenly not getting enough fuel. When the fuel filter is blocked, the car may not get fuel when tilted. The filter needs to be replaced. 3. Clogged fuel injectors: If the fuel injectors are clogged or the fuel pump fails and cannot deliver high-pressure fuel, the fuel cannot be effectively atomized, leading to reduced combustion efficiency and failure to achieve the desired performance. The fuel injectors or fuel pump need to be replaced.
