Some nights when it gets cold out after a warm day (say 65 degrees down to 40 degrees) my car will rev up and down like 5 times and then settle into it's normal range of 750-ish or so RPM. It seems like it bounces between 700 and 1000 RPM back and fourth a few times. Does anyone else experience this? It doesn't happen often, but it seems to be when the temperature differential is large from day to night. Any ideas?

Thanks for the info guys. I'll also try resetting the ECU. I also heard to get some fuel injector cleaner and put it in your tank and fill up with gas. It's supposed to also clean the throttle body, but I don't have much experience with this. Anyone had any luck with the products?
