eeeeeeee sound

When I take my foot off the gas I get an eeeeeee sound. Sometimes it fades away but most of the time it goes away when I get back on the gas. Is the problem my belt tensioner? If that's the problem is it an at home fix. I have a 2000 tj with the 6 and its auto. Thanks

My 01 has the same issue....I"ve changed the idler pulley which seemed to be the most obvious answer but no luck. New belt, same story. Your's could be one of these....I'm headed to the A/C compressor or clutch fan next. If you figure your's out let me know.

It is most likely the throttle body.

Sounds like a vacuum leak. Is it a whistle or screeching sound ? My sons has a intake gsket leak that only happens when its cold. Sounds like a whistle.

It's a high pitched eeeeeeeeeeeee that fades away until this mining I thought I could only hear it inside but I heard it while it was warming up this morning (-14) with wind chill. But this sound has been happening for awhile. In all weather. I thought it was a bad ground from an aftermarket stereo so I've let it go but my buddy head it this morning so I figured I'd ask the experts

I've had the same issue for several months. Seems to be dependent on wheel speed (IE, as I slow down to a stop it gets quieter and goes away), and is totally independent of engine speed (so I don't think it's a diff, or anything to do with the transmission as shifting to neutral doesn't stop it). It goes away within a couple of miles of driving. I was wondering if it was something at a wheel, but I was told the last time I had an oil change that the serpentine belt is going to need replacing soon... just doesn't seem like that would be directly responsible.

^^that is the same as mine it fades away as I come to a stop. It doesn't happen every trip I was looking on rockauto.com last night and I think I'm going to change the belt and the tensioner pulley and the idler pulley to tart with. I'm about to roll over 100k and I'm sure they are original parts.

When I had an "eeeee" sound that happened only when I was off the gas, it was my intake manifold gasket. That and the fact that only two out six of the bolts weren't broken or missing. Is your idle speed where it should be? Does the "eeeeeee" sound like it is being made by Barry White, or Ella Fitzgerald?

My bad, I see you said it is high pitched. I was chasing after pulleys and tensioners too at first. Check your IMG.

As hellkatshockey says, it sounds electrical at first - like ignition interference over the speakers. The first time I heard this my reaction was to shut off the stereo and see if it went away.

2002 4 cyl automatic here. I have a similar eeeee sound that happens when its cold outside. Comes and goes. fades out by itself. Sounds like speaker feedback. Doesnt do it in warmer outdoor temps. Everything runs ok tho. Doesnt do it when in idle, just when driving. no clue..

I've noticed mine more in colder temps but has happened in all weather. I let it run for about 10 mins in the morning and have walked outside twice now and heard the noise. Today we took a look at the belt and pulleys and I "could have" taken the serpentine belt off with just my hands with little effort needed.

Just noticed the same noise in my 2000, 6cyl, 4.0 this morning and when out at lunchtime. The sound would only be present when I was off the gas, and each time faded away after about 5-10 minutes. I'm thinking air intake related....???

Same thing happened to my 99 6cyl. The sound was driving me nuts. I just tightened a few bolts on my exhaust manifold and the whistling went away thank god. None of the bolts seemed loose, but just tried to tighten them a little.

Well I finally got around to working on the jeep. Changed the idler pulley which was bad and that didn't not take the noise away. Then I tried to change the belt tensioner but stripped out the torx bolt that holds the tensioner on. (Man I hate torx bits/bolts) the pulley on that is also bad so now I have to figure out a way to get this bolt out so I can replace the whole tensioner. Mean while I still have the eeeeeeee sound

I finally got the belt tensioner off had to remove the alternator then the bracket that the tensioner mounts to used a grinder to make a slot for a flathead (all because I rounded out the torx bolt to start with) after replacing the tensioner and the Serp. Belt I still have the eeeeeeeeee sound. The sound is there when I take my foot off the gas and usually starts when the jeep gets to normal operating temp. Also the sound goes away as I decelerate to under 1000rmps. I'm being told that it could be the water pump going bad? I'm at a lost for ideas and its only getting warmer out side so now everyone will hear it as we come to stop lights. Hide:

Then its something electrical thats feeding through your speakers, that's my best guess at least.

Ok so it's been awhile since any update on this thread but a couple weeks back I was playing around in the snow and blew a brake line. While the jeep was in the shop getting all the lines replaced I started talking about my eeeeee sound with the mechanic and he said it might be my IAC getting stuck which might be why the sound goes away when I push the gas again. He told me he would take it off and clean it for me. After leaving the shop the jeep has only made that sound twice (down from every time I took my foot off the gas in cold weather) I believe I'm just gunna change that part and possibly the throttle body if that would be needed.
