Specs show 23ft lbs, so I cranked her to that and took it for a drive. No whistle. WHOOHOO! But I'm skeptical it was that easy to fix, I'll keep you all posted. Avallanche thanks for posting again, didn't mean to steal your thread... if you do get around to that picture I'd still like to see it. Maybe the next person who comes looking for an answer to this problem will be thanking us.


I have been trying to solve the whistle problem for about six months now. I read this thread and post by youthpastortodd and saved it to my favorites. The other day i showed to my neighbor and we adjusted the bolts. Sure enough, the one closest to the firewall was loose as a goose. It's been a week now with no whistle. Thank God for His provision through this website!!!!

 

I am sorry to wake up an old thread like this but I was having the same issue and I will try this in the morning but I was wondering if after fixing this did you notice any change in performance... such as did it idle better, did a check engine light go off... etc. Thanks for the info BTW.

 

ALRIGHT GUYS!! I have figured it out. I have been having the same problem for a long time. My mechanic finally figured it out. You need to replace you "idler pulley" it is about 36 bucks and about 40 for labor. I havent had it whistle yet.

 

mine whistles thru my k and n at 1/4 throttle. its normal to me

 

I was wrong... It didnt fix it... It whistled this morning...

 

I don't know if you read the whole thread but the fix is a page back

 

I LOVE this forum! I have the whistle on my 2000, gonna tighten up those bolts tomorrow =) I'll let you know...

 

Hey every one, I have a 2000 xj sport, lifted, tires...... Same ANNOYING whistle for months now. I will check those bolts 2moro. I have been racking my brain and then I found this wonderful thread. I'll post back and let u guys know if those effin bolts were loose......

 

Don't no if this was already said but check the gasket under the throttle body. And make sure the throttle body is tight

 

Just checked that an hour ago after work, its tight. I got cold so I'll check the bolts 2moro. (No garage) lol

 

Did you ever figure out the solution, I am having the same frustrating problem. You could also contact me at my email rdelligatti@verizon.net.

Thanks!

 

If this isn't it, the last annoying whistle I had was the U-Joints on my front driveshaft. It made a high-pitched whistling sound like the one described here.

Best of luck.

 

my throttle body whistles at 3k rpm, i never bothered to try to fix it cause it sounds cool lol, it happened after i cleaned the throttle body

 

I wish more Jeep sounds were 'cool'
