What Causes a Car to Lack Power?

[OGage]

Reasons for a car lacking power: 1. Aging ignition coils or spark plugs not replaced for a long time, resulting in insufficient ignition energy; 2. Fuel system failure leading to excessively low pressure; 3. Excessive carbon buildup in the engine, causing poor fuel atomization; 4. Engine sensor failure; 5. Damaged catalytic converter or turbocharger. In manual transmission models, clutch slippage can cause the engine speed to increase without a corresponding rise in vehicle speed during acceleration. Dual-clutch automatic transmissions can also experience such faults. Issues like torque converter failure, failure of the lock-up clutch to engage, excessively low transmission system pressure, or faults in the transmission electronic control system can also lead to a car lacking power during acceleration.
