First, I know this is a long shot, but Im hoping just maybe someone knows what Im talking about.

First Ill describe the noise. Imagine a little propeller crop-duster air plane....

I can only hear it really good when Im driving through my twisty-street neighborhood at slow speeds.

I wouldnt say its "LOUD" but its very noticeable, and it just started doing it...

Im only going less than 20mph, and I only hear it while im on the throttle, let off the gas it goes away.

It basically sounds like an additional hum to the normal engine hum if that makes any sense..

exhaust leak? when the car is cold try putting you hand over the tail pipe and see what happens

If you rev the car at the same rpm that this groan happens, does the groan repeat? Or do you have to be moving?

How do your tires look? Any unusual wear?
Is your oil level ok?

SOLVED!!!

It ended up being the acc belt....

Whenever I hit that RPM, the belt would resonate. But what actually caused this was a loose alternator pulley!
