When you say uneven idle, do you mean the engine doesn't tick over smoothly or there is a bit of a vibration that sort of comes and goes?
Reason I ask is if its the latter, you may be in the early stages of DMF failure. If its vibrating slightly at idle, try dipping the clutch as its in mid vibration, and see if it improves slightly. If it is the DMF I hope you have a large wallet or an understanding bank manager.
