Not gettin gas

This is my first post on FordTruckEnthusiast. I have been just kinda checking it out and didnt really have anything to post until now.

I have a 99 F150 Supercab 4x2 w/ a 5.4 w/ about 95K miles. Lately when Im driving and push hard on the accelerator, it acts as though its not getting enough gas, sorta stutters. I replaced the fuel filter over the weekend and had replaced the IAC valve about a year or so ago.

Any sugesstions on what the problem is???

BTW I've only noticed it on acceleration

Thanks

Welcome to the forum.
I would try cleaning the MAF. And like above, how old are the plugs?
