Light fluttering sound under load
Hey all, I just got an 02 SiR (K20A3). I haven't driven a Civic in quite a while before this, so I'm not sure on this. I'm getting this light, high-pitched fluttering sound. It's not a rattle, squeal, or vibration; I would liken it to a constant cricket chirp, but quieter.
Some troubleshooting info:
Some troubleshooting info:
- Consistently heard under load, any gear, any speed, any RPM
- Heard in neutral, but much quieter
- Does not change pitch or volume with revs or throttle position. It's just on or off
- I can only hear it from the interior. If I pop the hood and rev it by the throttle cable, everything sounds normal.
- Everything else is normal, no power loss, runs smooth

Does it change with clutch position? i.e. clutch in, no sound, clutch out, chriping? Sounds like an input bearing or throw out bearing if that's the case.

If I listen very closely, I can hear the sound progressing upwards and downwards corresponding to the opening and closing of throttle. Also interesting, I can hear it somewhat when I rev in neutral while moving, but almost not at all revving while parked, which makes me think it's just air movement. Maybe this is just the way the intake sounds on this car and I'm not used to it?

a video would be helpful. Also check that any splash guards and engine bay plastics are secured. Any modifications to the intake? (Short ram / cold air?) My short ram whistles a bit hahah

Sounds like CV axles to me. Jack the car up and give eash axle a solid shaek forward-backward, in-out and see if the rattle a lot. Notice it in the sharp turns?

I was thinking maybe exhaust leak, but I thought those tend to be a lower, more rattle-like sound.

CV boots are fine.
If I bend down by the driver's side wheel, I can just barely hear it while it's idling. Maybe it's just the intake?

Hello,
From everything I am reading, a clicking when making sharp turns at low speeds seems to be the CV Axle. from the sound of it, it is coming form the drivers side. I am trying to get a hold of a replacement, but none of the parts stores have one in their system. I have a 2015 Accrod EXL V-6. If someone could point me in the direction of a part number and where I can buy it, I would be grateful.
