There are many reasons why a car may not accelerate when stepping on the gas pedal, and it cannot be directly determined. Low fuel pressure or air in the fuel line, poor signal from the air flow meter in the circuit, poor signal from the throttle position sensor, damaged ignition coil, delayed ignition timing, and incorrect spark plug gap (either too large or too small) can all cause the car to not accelerate when stepping on the gas pedal. Below is the relevant explanation: A clogged three-way catalytic converter could also cause this condition. Moreover, if the engine speed rises normally but the engine noise is loud, it might be in a neutral state without engaging any gear, requiring inspection of the transmission. If the engine speed does not increase when stepping on the gas pedal, a comprehensive engine check is necessary. It is recommended to visit a 4S shop for relevant inspections as soon as possible.
