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
