Check your front brake or upper control arms.

Vibration accures while at a complete stop waiting for the green light seems like my car is a little shaking. What can be the common causes for the car to be shaking all of a sudden?

I think you're being nick picking here. Your unique test condition doesn't occur under normal driving at all. If you hop in any car with 100K miles, put in drive rev to 3K and hold on to brake pedal you will feel a vibration is guarantee.

Another word vibration is expected when you put 225 foot pound of torque into an engine with old engine and tranny mounts, the vibration will then transfer onto the suspension but the suspension can't dissipate the vibration because you are holding on to the brakes.

Now, if you have a vibration at 3K RPM while driving then it's another story.

I would check the exhaust. It might be an issue with the placement of your muffler. When you put it in gear and the engine flexes your motor mounts the exhaust might be touching something causeing a vibration.

John has offered another on point recommendation - OP has done this load "test" before and after the only apparent change made to the car (new exhaust), something I never heard of or would do myself with an auto tranny, but ce la vie.
