i cleaned my intake manifold when i changed my spark plugs and the after effect is great. I used STP throttle body cleaner and sprayed all the intake pieces that had an oil residue. I have a Throttle Body Spacer so it kinda whistles around 2500 RPM's but now after i cleaned it it whistles just idling. Some guy at autozone asked me if i had a turbo. So if you have some spare time clean your intake manifold
