Today I noticed at exceleration a small cloud of whitish/grayish smoke from the exhaust of my LML, I don't think this is normal, I'm only running the GT Tuner, but everything else is stock, any thoughts as to what this may be, I'm hoping its not the beginnings of injector problems???
Whitish/grayish smoke stock LML???

check the degas bottle there were some cylinder head gasket improper bolt torque bulletins when I worked at the dealer
Mine sits and idles all day and if it is in a regen when I take off it will smoke for a little bit til it gets all the soot blown out.:thumb:
I don't think it was in regen, or had just finished one bc the message wasnt displaying, but I had to have a sensor replaced and it had to be manually defends at the dealership bc it went into limp mode last Thursday, I pulled my camper about 200 miles after that and haven't driven much other than that, hoping its just left over soot from that, so I drove it pretty hard for a couple miles and it sorta cleared up, stopped doing it, but I had driven stop and go and allowed it to idle quite a bit today so I'm also wondering if it coulda just been a lil build up burning off????
What's the degas bottle???, and its purpose? these newer trucks are all new to me, I know more about the classics than these new ones
It doesnt display the message unless it is close to getting clogged, If it is going through a normal regen it will idle around 900 rpm
Sounds normal to me. That soot that the DPF traps has to come out sometime, and when it is burned off it comes out as a greyish or blue ash.
