Why does the car feel sluggish when stepping on the accelerator?

[DiManuel]

Here are the reasons why the car feels sluggish when stepping on the accelerator: 1. Clutch problem: If the engine speed increases when you step on the accelerator but the car doesn't move, it indicates a clutch issue. 2. Throttle cable problem: If the engine speed doesn't increase when you step on the accelerator, it means no fuel is being injected, which could be due to a fuel supply system issue or a throttle cable problem. 3. Intake system problem: When experiencing sluggish acceleration, you should check if the intake system is intact. If it is, consider whether the intake system needs cleaning. Here are some extended details on related content: 1. Power: Power delivery is primarily achieved through the combined operation of the intake system, fuel supply system, and related electronic circuits and components. Therefore, when experiencing sluggish acceleration, you can check these three areas to determine if they are affecting acceleration performance. 2. Avoid flooring the accelerator: Flooring the accelerator only reduces driving time by 4%, but increases fuel consumption by 37%-40%. On typical city roads, the speed is usually maintained at around 50 km/h, with engine speed generally between 2000-2500 rpm. On highways, the speed is usually between 90-110 km/h. For every 10 km/h increase in speed, fuel consumption increases by 10%.
