    Hey Everyone,

    I was hoping someone might be able to help me diagnose a weird noise I just started hearing on my 99 v6 prerunner. It occurs a little above 2000 rpm, and under moderate load. If I push the pedal down more or back it off the noise disappears. I tried revving the engine in neutral and I did not hear it. It is most loud on the highway, when under a load like trying to accelerate up a hill at 65 mph. It sounds metallic, like something is vibrating. I don't know how to describe it too well, so I took a video. It's hard to hear in the video (much louder in person) but you can hear it best in the first 2 seconds. It's very difficult to tell where the noise is coming from, but it sounds very close - like its just on the other side of the fire wall. I am hoping someone will have encountered this noise before. Thanks in advance
