6.4 Cold Start

Post by HeavyDuty » Sun Dec 10, 2017 3:56 pm

My ‘17 6.4 has this weird issue at around -10 c
If I use remote start at around this temp. The engine cranks longer than norm (about 3-4 secs) then stumbles and burps a few times then dies. Of course then remote start is cancelled. I have no issues when it’s warmer. And it starts great at -20 or below temps. Has anybody heard or had any issues with this as well?

I have never heard of anybody having issues like that. That is definitely odd. I have never even used my remote start :lol:

So your saying it works fine when it gets even colder?

Ya. It’s starts fine when it’s colder. Just bumbles and farts when it’s around -10.

Have the dealer re-flash it. Something is wrong with your fuel-air map. :popcorn:
