Hi.

I have received useful information about EGR in the past from this site but this is the first time I have actually posted.

I returned from vacation and when I started my Accord I noticed a high pitched humming/whinning noise while the car was at an idle. The noise continues while accelerating and eventually decreases at higher speeds. It seems like it could be coming from a belt of some sort.

While looking under the hood the noise seems to be coming from the left side of the engine. Any ideas would be appreciated.

Thanks.
