6 months ago I had a set of F1 Flux 1 injectors put in my truck. Runs great but lately, the weather started getting cool enough to sometimes make the grid heater turn on in the morning. What happens when it doesn't, the truck starts to idle rough and throw out some whitish smoke and smells of cold diesel. Idle it up for a few seconds and goes away. When the heater comes on, it idles fine. Otherwise it runs strong awesome. Stock program and I just had it serviced a few weeks ago and all filters replaced. Ran some Meaner Power Cleaner through it and no change. Hooked up my trailer and ran the snot out of it for about 20 miles, no change. Suggestions?

 

I would check the cross-over (tubes that go into the head and are pressure fitted into the injectors) tubes for the correct torque. They might be a little loose causing a bad seal. When the engine is warm I assume it is fine.

 

Thanks, I did get new ones of those installed as well, will look into it.
