Start up really lumpy everytime

  1. #1
    A friends car.
    Everyone he starts the car there's a period whilst it's super lumpy
    Then it will sort itself out. It will do everytimr car is started about 2 mins if left to idle. If u drive it straight the way It will be fine. Buif u leave idling it will do it. It will go lumpy for about a minute then sort itself out and be fine. Any ideas? Changed coilpack and map and plugs.
