I normally don't drive it when < 50 degrees but it was 35 this morning. All was normal until I rev'd above about 5K and this whine started when the engine came back to idle and at a stop. It varied with rpm but pretty much went away after 2K or so. After driving on the xpressway for about 20 minutes it went away totally. Kinda sounded like a power steering pump but didn't vary when I turned the wheel. AC compressor maybe? It was pretty loud when it first happened. 96K miles. Any thoughts?
Thanks
