My buddy recently purchased a 2014 6.7L Cummins, and I wonder if I can get some advice.
This is during a cold start; temperatures are around 30-40 degrees Fahrenheit first thing in the morning.
Using remote start, the truck starts fine, then tries to go into high idle and begins to surge and blow black/blue smoke from the exhaust.
No codes or anything are presented. It does not do it if I manually put it into high idle through the steering wheel.
Has a RaceME tuner and no other modifications other than weight loss.
Once it is warmer after going down the road, it doesn’t do it anymore; it has a slight surge in RPM, but not like the initial start-up.
I have a video I am going to try and attach to show symptoms.
Any advice would be appreciated; thank you.
