check engine light was on this morning. Runs fine so far. What is your guess as to what it will be? I'll run the codes tonight.

 

I would love to tell you but my crystal ball is in the shop.

 

just saying take a wild guess for fun. Not expecting anyone to know the right answer.

 

What is the prize?

 

I would say it is a sensor code of some sort.

 

My guess is that it will run fine even further than 'so far'.

More than likely though your left bank cam phaser is letting go in your 5.0 eco motor, notorious problem.

Don't bother to run codes, I dare you to just leave it be so we can see how far it lasts.
If you are a Back to the Future fan, I'll call you Chicken if you back down.

 

I bet you need a new engine

 

And Tranny.

 

It's the code that says your trailer can never be too big, just send it already!
