Ok so last year at the end of the season my car started making a noise....sounded like it was time for a new belt and my idler pulleys were pretty much worn down....so I decided to change my pulleys first.....after I changed them start the car up noise is still there....so that's fine ....get a new belt put it in noise is gone....beautiful....put the car away for the season....this year take the car out no problems no noises .....1month later the noise starts coming back....it's driving me nuts....when the car is cold the noise is loud....after about 5 mins if driving it goes away....the noise gets louder as I give it gas ....then quiets down when I take my foot off the gas ....could it be that I need a new belt again? Maybe bearings in my pulleys? Maybe my belt tensioner? Does my boost have anything to do with it? Anyone have this kind of thing happen to them?
