Mine never did it within the first 1000 miles. It seems to begin after the engine has "loosened up" a little. Now at 4K+ miles it does it every cold start with the A/C on (jumping from 600 to 1500 rpm) and occasionally with the A/C off it will fluctuate, but less (900 to 1100 rpm). It does always stop after 20-30 seconds and has never re-occurred with a hot engine.
Once the engine has been running for a minute or so, the idle speed is absolutely steady and smooth at 600 rpm (indicated).
