I have an '06 XC70 with 130K miles on it, displaying a P0170 error code. On a cold start everything is fine, on a warm start after a short stop (such as a gas station) the car will initially idle rough with the revs surging from 500 to 900 RPM. Once the car is in gear and moving the problem goes away. Not an issue at highway speeds and not an issue idling at red lights once you have been moving for a minute or two.

Any help or suggestions greatly appreciated.
