I know it sounds like the tranny in the title, i know its not, because what happens is i can rev it up when its been sitting and havent drove it in a little while with no problems but if i try to drive it, it cant push out its like it bogs down...and isnt getting enough fuel or something...and then when that happens even when its sitting in neutral idling it will idle fine but it wont rev up above a certain point, im thinking my fuel pump is going but its just not completely out yet??

Maybe??

Help me out give me some opinions, or facts...anmything to help would be appreciated,

Thnx
