Why Does the Car Accelerator Feel Heavy?

[StMakayla]

Car accelerator feeling heavy can be attributed to the following reasons: 1. Excessive engine oil, which increases internal resistance during engine operation, resulting in slow engine speed increase when the accelerator is pressed; 2. High viscosity of engine oil, leading to excessive internal resistance during engine operation, preventing the engine speed from rising quickly when the accelerator pedal is pressed; 3. Issues with spark plugs and ignition coils can also cause the engine to lack power and accelerate slowly when the accelerator is pressed. Spark plugs should be replaced periodically. Not replacing them for a long time can lead to increased electrode gap and excessive carbon buildup on the electrodes. When selecting engine oil, it should be chosen based on the engine's technical characteristics.
