I can hear this noise when sitting in park and when im on the gas, but when i let off the gas it goes away. Its sounds like a fast clicking noise. It sounds like its coming from under the hood in front of the driverside.

Start at 0:30. You can tell when im on and off the gas. Might have to turn up some.

 

i hear the same noise in my 01 cl, ive been wondering what it was also

 

It's the A/C compressor belt. It's most likely too tight like mines is. I took it to the dealer and that's what they found out. If you want to do it for cheap, just have your timing belt done. They will already loosen it for you. Whenever you slightly tap on the gas, you hear it correct? Mines so loud you can hear it when it's been driven (like when you put it in park).

 

almost sounds like a relay or solenoid, where is it comeing from underneth the hood (driver side or passenger side???)(front or back) and does not seem rpm dependent
if it is coming from the driverside strut tower, there is a solenoid right there next to the intake (an educated guess)
go out to your car, pop the hood , and maybe get someone to push the throttle to reproduce the sound and listen for it

 

driver side is that selenoid - passenger side would be ac belt tensioner
No sense waiting for the 105!! just replace that tensioner- runs about 85$-a year ago when mine was replaced

Should serve as notice to replace the timing belt tensioner with the 105~

 

mine was done at 90K and i did not have pay for it, previous owner still owned it then, but i know it was down right cause I DID IT (car was a customer's)(and the whole family are still customers)
