Hi everyone,

Since 2-3 months ago, in my Odyssey 2008, whenever I depress the gas pedal more than the minimum, so the engine somewhat revs up, I hear an extra noise coming from the direction of the engine, something between hissing and rattling. I made a short YouTube video at , the short noise can be heard 3 times on second 3, 5, and 7. What could it be?

thanks

 

welcome to the forum. difficult to hear any change in engine noise. possible you have an intake hose loose leak, rattling may be the cat shroud.
