I need help of the collective mind. There is an incomprehensible hum at a frequency of 236 hertz. I listened to everything possible with a stethoscope, including the car's muffler. The sound from under the bottom of the engine. When the engine speed increases, it disappears. Recorded the sound separately. I thought the fuel pump was going to be replaced, but it turned out it wasn't. MDX 2002.
