Quick question for a follow up Went out and cranked the truck. Ran fine until it warmed up(drove it about 5-6 miles) then it started the missing and wanting to die at low idle again. My question is: if it were a phaser wouldnt it run rough from the start and not just once it warms up?

Ran fine until it warmed up(drove it about 5-6 miles) then it started the missing and wanting to die at low idle again.
Warm engine = closed loop and reading all sensors and making adjustments based off what the sensors are reporting.
If you are getting unmetered air(that is what a vacuum leak is since the air entering the engine id not passing the mass airflow meter) then a lean run condition will occur causing what you are talking about.
Is the check engine light on?
