well I sprayed the back side of the idler with wd40 and my belt is brand new. It still makes that noise. It'* intermittant though.... It happens when I'm cruisin at 35-40mph and as I slow down the noise softens. Sometimes when I sit at a red light after it'* been makin the noise and I pull of when the light turns green the noise goes away. If it were a vacume hose wouldn't it make the noise at idle if I steo on the gas a bit while in oark? Cause this only happens when I'm driving. But my service engine soon light does keep comin on and then goin off. That code was p0171 I believe
