[RESOLVED] Engine creak upon start-up

[Jdiddy2k4]

So I started my car up a few days ago and then when I started driving I notice kind of a creaking sound upon getting on the throttle. I then hit it WOT and the creak got a little louder and then went away and didn't come back until the next time the car had been sitting for awhile. Does anyone know what this could be? It doesn't sound like a belt squeal and the engine light isn't on at all.

Harmonic balancer (crank pulley) separation or loose belt.
