Reasons Why the Car Lacks Power and Cannot Accelerate
2 Answers
Reasons why the car lacks power and cannot accelerate are as follows: Ignition system malfunction: For example, aging ignition coils or spark plugs that have not been replaced for a long time can lead to insufficient ignition energy, poor combustion, weak engine acceleration, and the illumination of the engine fault light. Fuel system malfunction causing excessively low pressure: Insufficient fuel injection can result in weak engine acceleration. Excessive engine carbon buildup: This can lead to poor fuel atomization, similarly causing poor combustion, excessive exhaust emissions, and weak engine acceleration. Engine system malfunction: This can cause the engine to enter an emergency operation mode, thereby limiting the engine's power output and resulting in weak acceleration. Examples include faults in engine sensors such as the oxygen sensor, air flow meter, crankshaft position sensor, knock sensor, etc. Signal faults from these sensors can cause the engine to enter an emergency operation mode, leading to weak acceleration.
Last time I drove, the acceleration was particularly slow, and the engine felt powerless when accelerating, as if stepping on the gas pedal had no effect. At first, I thought it might be due to hot weather or fuel quality issues, but changing gas stations didn’t help. When I took it to the repair shop, the mechanic said the spark plugs were severely worn out. After replacing them with new ones, the power was restored. He also mentioned that if the air filter is too dirty or the fuel injectors are clogged, it can also make the car feel sluggish. I suggest fellow car owners start with simple self-checks, such as checking if the tire pressure is appropriate or if the brakes are dragging, to avoid overtaking in dangerous situations. Poor acceleration can affect driving safety, especially on highways, so it’s important to address it promptly and not wait until a breakdown occurs to regret it.
