Why is there abnormal noise when accelerating the engine?

[LeLeo]

When the car engine accelerates, the loud noise is caused by engine overheating or problems with the exhaust system. Engine issues: If there is a hissing sound from the engine, similar to steam or air escaping, and the engine rapidly loses power after hearing this sound, the possible problem is engine overheating. Check the cooling system. When pressing the accelerator, if acceleration is not obvious and there is a lack of power, accompanied by a hysterical sound from the engine, this is most likely to occur when the engine is hot, cold, or low on oil. Exhaust system problems: If there is a hissing sound from the engine, similar to steam or air escaping, and the engine rapidly loses power after hearing this sound, the issue may be a blocked exhaust system, vacuum tube leakage, or breakage. Loud noises coming from the exhaust pipe, sometimes also similar sounds from the front section, mainly indicate problems in the exhaust system. Check if the exhaust pipe is cracked.
