What Causes the Noise When Accelerating Rapidly?

[OErin]

Rapid acceleration causing noise is due to excessive spark plug gap. Fuel supply system malfunction: When the engine feels sluggish during rapid acceleration, it is generally caused by a fuel supply system malfunction. It is necessary to promptly visit a 4S store or an auto repair shop to address the engine's fuel supply system, which can resolve the issue of sluggish and weak acceleration. Engine lubrication system malfunction: Other reasons for weak engine acceleration include engine lubrication system malfunctions, engine overheating; intake pipe leaks causing excessively lean air-fuel mixture; weak high-voltage sparks due to faulty spark plugs, ignition coils, or high-voltage wires; malfunctioning exhaust gas recirculation system; faults in the air flow meter, intake manifold absolute pressure sensor, throttle position sensor, etc. The specific cause requires detailed inspection by a repair shop.
