Default Gas Pedal Vibration

I just noticed this the other day. Very close to 1500 RPMs, I will get a nice vibration that can be felt through the gas pedal. I cant feel it through the brake pedal or the floor, just the gas pedal. It does this whenever I go through that particular RPM, and it doesnt matter what speed or gear I am in, but the vibration is only at the 1500 RPM mark. Any help/insight with this would be greatly appreciated before I break down and take it to the dealer!

Have any of you looked at the A\C system to see if it rattles? I thought it was a little wierd that it was only at a specific RPM.

Yeah jr, I checked tonight and we have the same problem. I wonder if its the fan coming loose or something of that nature, because it went on for about a second or two after i shut the A\C off. I just wanted to make sure that it wasnt anything serious.
