I have a 2005 4.4 v8, it is bogging off of idle but it's okay when in sports mode. Keep the revs up its fine but sluggish off of idle.
It has been fine until an oil change (engine oil) any ideas are appreciated.

This behavior started last week: no, to v-e-r-y slow acceleration when trying to pull on to fwy on-ramp, no kick-down when floored. Slight stutter @ 65 mph.
Idle is very good. Slow starts up to speed are fine.
I'm thinking my weekend project will start with new fuel filter... I don't...
