What Are the Reasons for No Acceleration When Pressing the Gas Pedal Hard?

[VonAriel]

Here are the main reasons for no acceleration when pressing the gas pedal hard: 1. Engine fuel system malfunction: If low-quality gasoline is used, it may cause the fuel pump to burn out, catalytic converter failure, piston malfunction, etc., directly affecting engine power. This can easily lead to engine stalling, no acceleration when pressing the gas pedal hard, and other phenomena. 2. Abnormal vehicle power: Engine power is generated by the coordinated operation of the intake system, ignition system, and fuel system. If any component malfunctions, it may lead to a decrease in engine power, resulting in no acceleration when pressing the gas pedal hard, body shaking, smoke from the exhaust, etc. 3. If the throttle position sensor is dirty or the voltage is unbalanced, it may cause electronic throttle failure, leading to no acceleration when pressing the gas pedal hard.
