Other likely causes:
- engine coolant temperature sensor (ECT) not providing engine temperature information to ECU (so ECU doesn't enrichen the fuel mixture properly until engine warmed up). See Electrical: Engine Sensors, Diagnosing ECT failures in FAQ
- vacuum leek (so ECU thinks appropriate fuel/air mixture has been achieved, but amount of air getting into mixture is higher than what it is aware of). See Engine: Fuel Injection, Troubleshooting: Vacuum Leak Diagnosis in FAQ
