Someone change the plugs on my "06" dodge ram 1500 4.7. It's running ruff on 2006 Dodge Ram 1500

The truck was running fine before the change, it's running ruff and the check engine light came on. I don't get it.

Check proper firing order 1st or possible damaged plugs either due to improper install or factory defect part.
Thank you for the input, I'm waiting for the dud to show up to re-check his work. I'm so made mad, that's my babe.
