signum 2.2 direct lumpy idle

[mcd840]

Hi, as above, have noticed that when the car is started from cold the idle is quite rough, although the rev counter does not fluctuate there is quite a rough vibration through the car, this does seem to sort itself out when the car is up to temp but still think it could be alot smoother when the car is warmed up, there is no eml or fault codes present.

cheers
