so i rebuilt my engine..first startup whining noise coming from throttle body area...the noise is whining when ya give no gas...so when vaccum is present...but when ya hit the gas and the boost kicks in the noise is gone till ya let off the gas again...ive cleaned the iacv with cold carb..replaced hose to iacv along with new clamps..and torn apart intake mani a couple times to find problem...if anyone knows what my problems are please let me know..thanks
