Just had my fuel system (ALL of it!) replaced two weeks ago due to a long battle with contamination. The truck runs great when warm, idles a hair rough, but not bad - worse in gear than in Park or Neutral. Problem is, when I start it cold, I get about 20 seconds of white smoke and a bad miss, like a dropped cylinder. Very little injector noise or any type of clatter, no codes thrown. No fuel in oil that I can tell. Fuel pressure to the CP3 sits good at 20 psi. While it has dropped into the 20's for a couple nights here, daytime temps have run in the high 60s - still "dropped a cylinder" when I started her after sitting at work all day.
Any ideas? Valve(s) out of adjustment, cold idle circuit (do CTDs have those?) or ECM/sensor screwed up......???
This just doesn't make sense to me - with all new parts from the tank to injectors and all in between (thank heaven for State Farm insurance!), and less than 1K miles, running no pressure mods, and getting my fuel from the same Flying J pump as a buddy who's had no problems - I'm lost. Anybody know a diesel wizard near SC?
Thanks for any help!
