help needed

[deanski]

Hi all. Just started the car up and idle was ok but then dropped to about 700 for a split second. The car coughed and sputtered all the way home. It pulled ok when i nailed it but it was very rough on part throttle and when setting off. It was in awesome this week and no codes where showing and the injectors were all balanced so this is recent. Any ideas chaps?
