Coolant temp sender could be culprit. It could be commanding too much fuel all the time, especially when it's cold. If it smells rich, that could be it. EGR is also suspect on these. Usually you can take that off and clean it up with some carb cleaner. I would verify the vacuum lines with some carb cleaner also.
