Default 03 5.4 Misfire on takeoff

So I swapped out my coil pacs, fuel injectors, intake manifold & gaskets along with my spark plugs. While driving she runs perfectly fine, but upon take off she Randomly studders a little. Does anyone have any theories or experience with a problem like this? Can’t hear or trace a vacuum leak, bolts on the intake are to torque spec.

Yep could be the brand used or a old clogged fuel filter.
