Anywhere from 3K to 4.5K rpm's(and sometimes when I idle), my car(98 gsr) produces a rattling/tinging/vibration noise that appears to be coming from underneath the car. I have put the car on my rack and for the life of me, can't figure out where the noise is originating. It is really annoying as the noise takes away from the sound of the engine.

Any ideas where it is coming from? Is this a common problem in Integra's?
