Rough idle RPM dependent?

Does anyone else feel like the engine runs rougher at certain RPMs? It seems to me that when idleing(750rpm), my car is running rougher than if I raise the RPMs just a tiny bit to 900-1000. I also get the same rough feeling at 2000rpm.
You have to expereince this while in neutral, not while driving because there is too much feeling from the road and bumps.

Unfortunately, I have experienced this as well. Mine doesn't idle rough all the time, just occasionally. I can definitely feel a little to much shaking at 750 rpms. If if I turn my AC on, I can watch the needle go from about 770 rpms down below 750 to about 730. When it goes below that the car shakes a little and goes back up. I doubt this is normal, but I will be taking it to the dealer in about a week for other little problems and I will ask them about it. Anyone else?
Yep, I noticed it a little this morning while parking in the garage - it's a very slight shaking when at idle. I have 53K miles and am on the stock plugs/wires. Maybe I'll start by changing these out first.
Mine is too doing the same thing.
