Yesterday coming home from work I heard a whistling sound when I accelerated. Today it's worse. I only hear it at high rpms. Does anybody know what is causing this.

 

I would check your vacumm lines and then maybe start it up and check for leaks in your exaust system

 

Its called "Spontanious Turbo Interformation" otherwise know as "STI". Much more common on foreign made cars tho.


Either that or you've got an exhaust leak maybe... Crank your jeep and rev it with the hood popped from the throttle body, make sure it just doesnt sound like its coming from the exhaust.

 

I did that when I got home today and the whistle is coming from the tail pipe.

 

The whistle is coming from inside the tail pipe

 

I want to say it is. I'm fixing to get someone to help me for a sec to make sure it is coming out the tail pipe.

 

I dont think your exhaust is literally whistling out the tail pipe its probably just a leak where the muffler joins or something but I may be wrong

 

Oh yeah it's coming out the tail pipe. I hope it ain't the honey comb stuff inside the cat breaking up.

 

hissing/"whistling" is usually a sign of a restriction, which is what would cause a whistle. if there isnt a break or a pinched exhaust pipe somewhere, my guess is that the catalyst has melted. Did your jeep ever have a misfire for an extended period of time?

 

I just cant imagine what thatd sound like
Id take the exhaust off and check before I worry to much

 

Is the exhaust stock

 

I'd just call it a "free turbo sound maker" and be done with it

 

Xxx2

 

Yeah stock and I found the prob.



And that's why the exhaust sounded funny at times and there was a loss of power at times also. This sucks.

 

Well. Better this than something major.
