As vehicles age, many people encounter issues with insufficient power and slow acceleration. If there are abnormalities in the engine oil system, such as a decrease in gasoline pump power or clogging of fuel injectors, it directly affects the vehicle's power output, leading to difficulties in smooth acceleration.

Additionally, spark plug issues are also common. When spark plugs' ignition performance deteriorates, it directly impacts the engine's efficiency, thus affecting the vehicle's power performance.
Furthermore, problems in the engine's intake system can also cause insufficient power. If there is severe carbon buildup or blockage in the engine's throttle valve or filter, it limits the intake of air, thereby weakening the vehicle's power output. Moreover, if there's an anomaly in the engine's cylinders, such as one cylinder not functioning properly, the vehicle will noticeably lack power during operation.
Apart from the engine, tires can also influence the vehicle's power. When tire pressure is low, it causes tire deformation, which in turn affects the efficiency of power transmission in the vehicle.
