I have a '07 G6 GT that I inherited from my 87 y/o grandfather when he past away in January. Yes, it's red because what other color would an 87 year old man drive. Within the last 2 months I've started noticing a high pitch whistle/noise when I accelerate. If I back off the throttle its goes away. I thought it was brakes at first but I get no noise when I brake at any speed. Only when I accelerate. Anyone have any thoughts? Haven't brought it in yet, want to see if its a minor fix I can do myself.

Thanks.

Wasn't the weep hole. Turns out my idle pulley is bad and that stretched out the S belt. Oh yeah, both my front struts are leaking, at 25,500 miles.......................

I just tried a new serpentine belt and new idler pulleys, no change at all so I guess I am going looking for a weep hole before I take it to the dealer.
I was surprised that the belt was not in stock anywhere, then I saw how long it is. I don't think I have ever seen one so long before..
Due to the dealer cancelling my after market warrantee ("oops it was a clerical error") I now have to wait 30 days for the coverage to take effect.
arrghh...

I replaced the pulleys, belts, front struts, new brakes all the way around and I still hear the whistling. I'm now convinced its the exhaust after seeing many others post the same thing. replace the exhaust sound goes away. My suggestion is look at after market exhaust systems and not a GM one as you will probably wind up with the same crap product again. Now is your chance to get some throat for your G6.

Labor to replace resonator

It should take no more than an hour to get the bracing off and replace the resonator. There is no complex work involved. If they try to charge you for more than an hour of labor ask to know why and ask for them to show you. Unless there is rusting of bolts that would require more work to remove they are trying to rip you off and you should go somewhere else. It should cost no more than $150 for labor and the part which you can order yourself.
