I have a 92 GMC Sonoma 4.3L automatic 2WD, and it recently started makeing a whining noise. It starts as soon as I crank it and keeps going until I turn it off. Took it to AutoZone they said it was the Idler Pulley, changed that still makeing the noise. Also changed the Belt tensioner and the noise is still there, Any suggestions?
