Hey guys, I have an 08 gt with a jlt and a tune. Recently I started my car after I had left it outside over night probably around 20 degrees and when I started the car the next day there was this whistling sound coming from the front end. idk how to describe it but I will try and record the sound if it happens again. It has happened 2 or 3 times any know what this is?
thanks

 

JLT sucks in more air and makes a whistling/air sucking noise. Being colder, it was revving higher on startup, possibly causing you to notice this sound?

I know when I'm driving and have my foot on the gas, I can here it "whistling" as it sucks in air.

 

There's a TSB for that. The noise should go away after it warms up. I'll try to find it and I'll edit my thread.

thanks guys, I just wanted to make sure it's not gona cause damage to the car. It makes the sound twice for like 2 seconds each time right when I started the car if that helps

 

When I drive around and get on it I hear the whislting/sucking sound from the intake this is a different sound. But ya mayb its because it was cold

 

I've also got the JLT and I've noticed the same thing. It's nothing to worry about. With the engine cold I can hear a whine of sorts when I get on the gas, but it goes away once the engine warms up.

 

It's the fead idler pulley causing a whistling on freezing cold idle. There's a TSB out on it.

I'm getting my car checked out at a dealership sometime over the next couple of weeks. Happens on mine after it sits in the garage on a sub-freezing night. I don't have any intake upgrades.

 

thanks alot guys. Im going to bring my car in for service soon, do you guys think I should bring this issue up or just leave it alone

 

anyone???
