[QUOTE="Black AOD, post: 1356672, member: 16536"] So question for all you experts....after getting my truck back, on cold starts after it has sat over night for roughly 10-12 hours, it starts obviously a little rough since its cold, then during idle it begins to output fairly decent amount of white smoke from the exhaust. The idle gets rough and a little choppy. This is the exact behavior I had before when one of my old injectors was bad and was sticking. Anyways, Once you drive the truck and get it up to warmer temps it clears up and is fine and runs how it should. Should I maybe be checking the injectors again or is it just as simple as a possible revision in tuning on cold startup is needed ? Sort of worried it's an injector FYI - set of injectors were bought BARELY used with 2-3k miles on the cores. Sent to RCD for inspection and flow testing and balancing. 6 injectors amazingly had to be replaced, 2 were deemed fine. 6 brand new injectors with 60% nozzles and the other 2 were tested amd balanced and sealed and already had good 60% nozzles. So 6 are brand new and 2 are just barely used. And all of them were gone through by RCD within the past 3 months. Sent from my VS990 using Tapatalk [/QUOTE]
