    sounds like a coolant temp sensor to me but take it to your dealer and have them check out the fault memory to be sure, coolant temp sensors have been a bit of a problem recently!!

    As Andy says I be inclined to look at the coolant sensor as this is a common problem and gives the symptoms described, as the ECU alters the fueling and retards or advances the timing dependent on the coolant temp...so when cold it maybe that it puts less fuel in than it should because it sees a high coolant temp. The coolant sensor is pretty cheap around $20 I think you'll find.

    Other things that you may want to do, which are cheap and easy is fill up on a high octane fuel and put some fuel system treatment in with it, this should clean up the injectors/system and you may notice an improvement in running anyway even if it doesn't cure the problem.
