What to Do When There's a Hissing Sound Upon Heavy Acceleration?

[Aubrey]

If there's a hissing sound when accelerating, the first step is to inspect the vehicle's intake system for any air leaks. If found, replacement or repair is necessary. Check the car's valves for gaps and determine if they are excessively large. If so, the valves need to be replaced or repaired. Inspect the engine belt. If the belt is worn out, it may also cause a hissing noise during acceleration, requiring prompt repair. If the car's catalytic converter is damaged, it can disrupt the normal operation of the internal airflow system, necessitating immediate repair.
