S80 Engine Whine

My engine Whines when it gets warm. Only when not accelerating. The noise is caused by the engine sucking in air through the filler cap. Any ideas?

Sounds like the Idle Air Control (IAC) valve. Think it is a fairly simple fix. Tech can give you the particulars. Pressure is on Tech
