Hmm..., I don't know what would cause that, but my car sometimes shakes pretty violently when it's warm, although it doesn't do that cold. Actually, it only seems to do it after lengthy highway trips, and not all the time even then. Lengthy being 100 miles or so.

Is there maybe too much fuel going into your engine at these times when it idles to 2200? I'm by no means an expert, so hopefully someone with greater knowledge will reply. I'm curious about this now.
