[QUOTE="Dzchey21, post: 573786, member: 63"] When my truck had oringinal nozzles on the injectors it would do it only when it was pretty cold, like 0 degrees or so, and some tunes were worse than others. I found if i would kick the truck into high idle almost instantly that it would be ok once the truck was warm. Eventually i ended up putting another injector off ebay on it, did the same thing, got another injector, again it failed, put a ford reman in, and it was good ever since. The reason why its coming and going is the truck does basically performs a self test on the injectors at idle and makes sure the power balance is correct, if its not it eventually starts adding or pulling fuel from that injector untill it gets a missfire code. It should throw a contribution code first, then a missfire after probably about a minute of idling. At any rate try the things we discussed to make sure that the injector body itself is the issue and not the nozzle (not that i have ever seen a bad nozzle) and then go from there. Also i didnt tell you last night after you swap nozzles or injector bodies just run it with the valve cover off for a little bit at an idle, that should be long enough to tell you what is going on. and you wont have to go thru all the work to button up the engine just to tear it apart again to figure out what is going on. Write down all your info too, if you swap 5 with 1, be sure you note where the nozzle is and where the injector is, its easy to mix things up and make things worse to diagnose. [/QUOTE]
