Scary Whirring Noise!
i got my car running smoother today i reaplaced all the gaskets and suddenly i started her up to get the no idle problem fixed and whenever i let of the throttle it makes this loud whirring whistle noise. sounds like the squealing noise of belts . so i tightend the alternator belt ( only on on the car now) and it went away but then came back , but the sound is coming from the back of the throttle body (where the cable connects to the pully...it scary sounding and it only happens when i let off the gas

also, make sure both surfaces where the intake manifolds meet eachother and meet the block are completely clean and free of all old gasket and debris. also, make sure you tighten all bolts in their correct order and to the torque specs
