Noise is heard at idle, but goes away with throttle tip-in...Heard in park or drive...Much louder when A/C is turned on...Runs beautifully, no issues from noise...

is possible that either a pulley has gone bad or its the a/c clutch making the noise
Thank you. I was thinking about the A/C clutch. Will look into it.
