Engine Feels Flat

[mavery4]

I Have A 96 4.3 For My Wife But The Pedal Feels Hard To Push To Get It Going I Don't Mean Its The Linkage. Everyone Tells Me To Get A Tune Up But It Doesn't Miss Abeat Its Just Slow I Thought Maybe The Cam Lobes Were Worn Down But Lately I Wonder If The Timing Isn't Advancing I Ran A Vacum Test For A Plugged Converter But There Was 17 Lbs Vacum I Would Think That Was Fine
