rough run on cold start(and smoke)
hi, im new to diesels and just got my 06 6.0l. i have had it for about 2 months, it has arp studs, exhaust, egr delete, and sct programmer. when i bought it, it would run rough for a few seconds puff some smoke then clear out and run perfectly fine.
i did a power balance on a cold start found #1,7, and 6 to be at fault. replaced those injectors, pulled out 3 and 5 while doing tht side they were new. so i replaced the orings and put them back in. truck now in the morning runs rough for only 2-3 seconds but puffs a little back smoke followed by whiteish blueish smoke.
my question is this normal? or could it be related to the programmer? any ideas would be helpful. thanks
