Engine Performance problem
1991 Chevy S-10 Two Wheel Drive Manual 140000 miles

i have a 2.8L s10 5 speed. has new plugs, wires and distributer cap. I recently changed the fuel filter and alternator.. when idling it seeems to run fine (runs smooth n does not seem to miss at all) n seems 2 have a lot of power when revved, but when put in gear it does not seem 2 have the acceleration it should.. when i make it to 60 (which sometimes takes a while) it loses power goin up hills n slows down. i usually have to drop it in 4th to speed back up then go back to 5th. ive been told a few different things that could be wrong.. What do u think?? thank you
