ok so about 2 months ago my I began the necessary tune up of my fuel system by getting my IP rebuild by a reputable injection shop. then I did the injectors a fuel line return kit, fuel filter, lift pump and most recently with the assistance of my trusty mechanic we tracked down an air intrusion coming from the failing water fuel separator. Anyway after warm up it runs great now but on initial start up it smokes like a tire fire only its more along the lines of whitish grey smoke. The frustrating thing is before my IP went bad and began all this work it ran clean as could be with only minor smoke on a cold start but now my whole neighborhood suffers when I start my truck. one other symptom is the idle on a cold start is a little rough but its not terrible. Like I said im extremely frustrated after dropping so much cash and having it worse than before . any ideas please help.
