Might want to post this question in a teck area for your F150. Also add in your post all mods, tire size, etc.

PCV valve, could have a leak. Also could be a COP.

I would say clean the mass airflow sensor with an appropriate cleaner, that should take care of it. also you didn't list any codes, is the check engine light on?
