Default 2006 2wd v6 300 code for random misfire

I took off the upper air intake to expose the coils. I tried to pull them to see which if any were bad. It would not hold an idle. Someone suggested I change the air intake.
Thoughts?
Anyone know of a video tutorial on changing the air intake valve?

It is most likely going to be a plug or a coil that has to be replaced . I doubt its a air intake issue./
