Thought you guys would get a kick out of this. I filmed the car during one of it's high idling episodes. When i drove the car prior to and after this video, it was knocking like crazy, but i did not get that on video. Skip to about 35sec into video....you'll also notice my foot is not on the pedal.
In case the video doesn't show up, here's the link:
