Hi,I have Tl 2.5 1996,I found a noisy part 184600 2910 sv3 12v,what is it?

 

Do you have any better of a description?

Where is the part? Do you know what it is?

What kind of noise, and when?

A picture would be awesome also.

 

Thanks for trying to help me,the part was a idle air control valve and other users wrote that the noise is normal on the Tl series,now I'm looking for alternator,and I found on Ebay one alternator with ident number 31100P1RA01 nippondenso mfg,is this part compatible with my acura tl 1996 2.5?
