Groaning/whine + vibration at around 1300rpm only- clutch in/out makes no difference.

[JJJames]

I've searched on this - haven't found anything.

What happens is that both while accelerating or revving the engine, or decelerating, as the rpm hits about 1300-1400 revs, there is a groan/whine, and a slight vibration that comes through the steering wheel and pedals. Any ideas? It immediately goes away when the revs drop below or rise above that level. No change in how the car drives/feels/sounds other than that. Whether the clutch is engaged or disengaged makes no difference.

Any ideas?

Check PS fluid, belt tensioners, and clean ICV valve

Mine does the same thing. Most of the threads I've ran into here have said its normal for these motors.
