Hey guys, any of you having a cold start issue with your 6.0? Does it seem to smooth out after a min or two of driving. Its probably the spool valves sticking in the injectors. There is a newer reflash that works wonderful on this problem. I have actually had trucks come in on a roll back, get pushed in the shop, get a reprogram and fire right up. Down side to this is if you let it go on for a long time it will eventually cause damage to your injectors. Any questions let me know.

 

Good info. Thanks, dude.

How Many Miles Is Too Long?

 

As soon as it starts is best, Even if its out of warrenty its only gonna cost you 1 hr labor. Remember this is only free under base warrenty 3/36 not engine 5/100. But if you drive it like that for several thousand miles you'll start to trash them.
