I have a 2006 ford f150 lariat and i am having a low end acceleration problem. Best i can explain it is that it kind of hesitates and is a little jumpy when getting up to speed but after you hit like 45+ its fine. Anyone have any ideas of where to start looking?

 

Fuel filter first. With no CEL or thrown-codes, could be an injector or COP issue. It could even be a vacuum leak.
