Help me diagnose 22RE engine whistle (with video)
Hey guys, my 22RE runs great, except it makes a whistling noise every once in a while. I wish it was constant because then it would make it easier to diagnose. I luckily caught it on video when I was changing my oil the other day. What do you think is wrong?

Mine sounds like that at around 1K rpm and 2500+. I like it. Take a look inside the air filter housing on the bottom there should be a little tube that goes from the outside and directs air 90* from the inlet. Mine is gone and makes that noise. I bet yours is missing as well.

mine does the same. the following is only WHAT I HAVE ALWAYS FIGURED THE SOUND WAS, not the actual reason. thinking something to do with the air flow sensor/ filter. basically when you rev the throttle body opens. air flows. when you let off the throttle body closes though the motor still wants some air. so this sound is the re verb/echo of air being pulled past (and bouncing around) the throttle body and or air flow meter. when the butterfly (throttle body) is open the air flows and with the butterfly closed the air becomes turbulent and gets pulled through the butterfly at the same time.
The sound is very noticeable on a civic with a cold air intake/ cone filter with no other mods. you usually can't hear it in this application cause an exhaust or turbo or whatever is louder.
also looking back at other posts, the removal of that elbow inside the airbox (in my experience) will make this louder. or a cone filter.
