mrz 01-28-2006, 01:25 PM Have an '04 lly when idling at a stop sign the truck will start to idle rough an really start blowing white/blue smoke out of tail pipe the truck is warmed up at this time. It does not do this all of the time, had it at dealer for problem say they can find no problem. Has anyone incountered this problem? 66flh 01-28-2006, 01:48 PM Injectors? IdahoRob 01-28-2006, 02:40 PM I did. Had them do the lastest reflash. That fixed the problem. They didn't think it would work, but I asked them to "humor me". Problem solved. mp18d 01-29-2006, 10:14 PM Bad injector! Mine did the exact same thing and dealer replaced #8. Fixed it.......Numerous prior comments about the same thing here. Good Luck!
