Incorrect; to high or to low idle speed, no noise! Have another "mechanic" check it out!
when I accelerate the wining gets louder /matches engine speed ,,, could it be a bad idler pulley making this noise ?
Yes, have it checked by a "mechanic". Easily tested for any drive belt system componet problems, mechanic will/should know what to do. You are not equipped to do this!!
What kind of symptoms are you having? What is the noise you are hearing?
just had the altenator replaced and my mech. took off the iac and said he cleaned it ,
