Hello all, 2015 RAM 6.7L Cummins, entirely deleted.
I have been having injector issues over the past two years.
I replaced all my injectors with BD diesel reman stock replacement injectors.
After replacing my injectors, my problems went away, but now about six months later, every morning I start my truck, my intake heater doesn't come on because it is 20- 30°C outside.
I'll start my truck, billow white/Grey smoke, and miss fire terribly for about 30 seconds.
Then it goes away and doesn't return until I shut my truck off and leave it for 8hrs or so.
If I start it and rev it up to about 1500rpm, the truck begins surging a bit while smoking more.
The last time I experienced this was only during the winter, and when my truck idled up because of the cold weather, it would miss fire and smoke the whole time.
So I thought it was safe to say it was an Injector. (Which, after replacing them, seemed to help.)
I have been running a RaceME Ultra tuner using the box tunes but have heard bad things about them.
Finally, I just recently purchased one of the custom Warp tunes from Ray.
The tune is fantastic, and my truck has more power than any box tunes I used to use, but it did not fix my issue.
I'm about to pull my injectors and send them to be tested and hopefully get a warranty.
Can anyone chime in with any ideas about why my injectors may have failed or if it sounds like a different issue altogether?
I don't warm my truck up anymore in this temperature, so it doesn't see any prolonged idle time.
The engine oil level is good and doesn't smell like fuel, so I don't think it's a cracked injector.
Thanks.
