Idle noise - 98 V70 AWD

My wife's 98 V70 AWD has recently (last 3-4 months it has become progressively louder) developed a noise at idle, which stops when the car is being driven. Initially, this was just while the car was in "park" and would subside when put in gear. However, over time, it has become louder and in addition to disappearing when driven, it changed pitch while shifting from park into gear.

What might be the cause? Is this something that can be easily fixed at home?

Thank you, Dave

Adjust idle speed away from something at resonance ?

Aha!? And how do you want to do just that in real life? With a computerised ignition and engine control?

Let us know!

Perhaps with the OBD programmer ?
