[conductor79]

40,000 miles on 2007 Sierra 4.8 over the last year it has developed noise in the electronic throttle body. Servce mngr replaced filter and re-programmed computer. Noise still ther when accelerating from 30mph. Any fixes for this? Thanks

Mine makes the whistling niose, I did take it in for other service and the service mngr noticed it was making the niose. Said they were talking to a service rep concerning this. Also, there is a bulliten out on this from GM. I can`t figure out why the niose was never ALWAYS there? Seems to have started in the last year.Very annoying!
