I have no idea whats wrong.....I havent done anything to her engine wise but im starting to get this noise thats getting louder.

Description:
When i drive my car around and its warm i stop at a stop light or at home the engine idles but all of a sudden the idle will dip about 200 rpms then a howling noise will come out of the TB. It will make this noise for a couple minutes then the rpms will bounce back up to 750 rpms and it will idle normal without the noise.... I have no cels no other problems eithier.

It seems that something in the IM or Engine itself is making that noise and spitting it out of the TB.... Ill try to get it on video and post a vid but any ideas what it could be....what could make my car drop rpms and make that noise???

anny acc. coming on (alternator, ps pump, ac) would make the idle come down... as far as the sound, I need a clip to tell. prolly just a resonance.

ok... heres the clip http://s30.yousendit.com/d.aspx?id=2WSJA6TA6DINI06CXOHX8TDFJL

It has 3 stages...
1)What my car with intake on sounds normal
2)The funny noise with the intake on
3)Funny noise with intake off and camera next to TB

You will notice in the 3rd phase the noise goes on then all of a sudden just stops which keeps weirding me out.

check all connections to throttle body. how does your throttle cable feel? has the car been running at higher temps? does the fan kick on when the idle jumps? possibly your iacv needs to be cleaned, i had that problem in my accord.

if all else fails..................

STOPPPP!!!


you dont need to adjust your TPS. you would get a CEL if that was out of whack.

you can clean the IACV (idle air control valve) nut then again, when they go bad, you'll get a CEL. still, cant hurt.

you should adjust your idle.... idle screw, and throttle cable.

adjust valves ;) but that doesnt have to do with the whistling

check vacuum lines.

also.... FICV (fast idle control valve) these can loosen up with NO check engine lights. remove it, clean it, tighten all screws.



besides that, your engine sounds okay.

after that it might be a little easier to help you. :)


good luck, but i dont think you have much to worry about.
