If that's all your experiencing, then keep driving the car for a few more days. A 100rpm jump is very small. The idle should settle down after you build up more KAM memory.
If you continue to have this issue, try the "idle relearn"
process. This will wipe your KAM memory clean so you can start fresh. Starting from scratch will smooth the idle quicker, after enough city miles.
Hope this helps!
