Clean, full engine oil, of the proper type is very important, so make sure you're not overdue for a change before proceeding. After that, you could try unplugging your ICP sensor to see if that makes a difference, but you'll probably end up needing to the it checked out on a scanner before you start throwing any more parts at it.

Since your issue is only in the morning, you really need to leave the truck overnight so the tests can be done on a cold engine. I'd start with a buzz test on the cold engine, then they can monitor things like ICP psi & IPR % while cranking in addition to just checking for codes.

Not only did the light come on it stayed on after the engine started for about 45 seconds. Not unusual in the morning, but it's freaking 106 degrees. So do like Jim said, check your GPR before you try anything else.

I am sorry about your weather but I am so glad that "high" the big red blob on the weather map finally moved to the West. It was so freakin hot and dry here for like two months.
