Idle Rev movement...
Initially had this problem from about 2000 miles onwards on my car, I know a few other guys have experienced the rev counter bouncing up and down at idle...CHECK YOUR COOLANT!
Had a low coolant warning light the other day that immediately disappeared once I started driving, well it came back on about two days ago, but again disappeared right away. Thought something must be wrong so I checked coolant res to find it wayyyyy below the "min" level.
Topped it up, and my rev bounces have stabilized at idle...give it a try if you've had similar issues!
