Check operation of the "Idle Speed Controller" or "Air Idle Controller". Either name is basically the same thing, what it does is control the fuel/air mixture from cold start until the engine gets warm. Replace fuel filter and complete tune up on engine. Then I would replace fuel filter and perform (or have done) a complete tune up on the engine.
