2016 F-150 5.0

My truck was throwing a P2005 code. I replaced the intake manifold, two actuators, and two solenoid valves. The fault swas still present. I took it into the shop and they said it was the position sensor. I picked it up and not 24 hours later and the truck flags another fault but this time for a p2006. I took it back in since it was still under warranty and they said it was a loose connector/ bank 1 actuator. I'm not certain what because I got two different answers from two different people. But for the moment it was fixed, and today after driving maybe 20 miles another fault flagged. When I got home it was p2006 yet again... the shop said they would take a look at it first thing in the morning. But where do I go from here? All components were replaced, shop said there was no vacuum leak, and the loose connector covers in my mind the electrical portion although there could be more. Not to mention the possibility of a faulty component from stock.
