Anyone heard of plugs making a whining noise
 

I poster a while back on here about a noise as i accelerate mainly in 5th but can sometimes be heard in 4th and 3rd. Was thinking it may be gearbox but the noise goes away immediately when you leave of accelerator or clutch it.

Someone on another site mentioned plugs?? Any truth to this?
I only ask as the noise only came into the car when the last fella who owned it got it serviced, and today it hesitated once in 3rd as i was building revs. No check engine and it aint done it again

Worried it could be something bad, can anyone shed light on this??
