6.0 Weird Start Up Behavior

See if y'all can help figure this one out...

This is on my 2005 Excursion. It's kept in a garage at night. Temperatures down here have been high 80's during the day, high 60's at night so it's definitely not cold starting conditions. This issue has just started within the last couple of days when she goes to start it in the morning.

Spits and sputters upon start up, runs rough. Within 20-30 seconds, definitely under a minute, motor smooths out and runs fine.

Since it smooths out and runs fine very soon after start up, I'm at a loss as to what it could be. This truck / engine has been virtually trouble free for its ~105,000 mile life so I'm not really up to speed on what 6.0L issue it could be.

Thanks in advance!

Do you have any way of checking codes? That would be the first thing to do. It's really hard to say what kind of problem there is until certain things can be ruled out. Could be anything from low HPO (High Pressure Oil) to injectors, low voltage at FICM (Fuel Injection Control Module), glow plug issues, etc.

I would start here.
One other thing keep good batteries in it because there are a lot of FICM problems coming up with all of these trucks that have old batteries.
