1984 GMC Sierra S-15 Pick up. 1.19Lit. Eng.?

Driving and got up to 50 miles an hour in 3rd gear, then shifted into 4th and it was runnining fine. Then made a left turn and truck started running poorly. Sputtering or a misfire type sound. Won't get up past 40. Replaced spark plug cables didn't work. Spark Plugs are only a month old. Any idea what this could be?

sounds like a fuel filter, but could be many things good luck

you say no spark coming from the plugs? it could be maybe water in your gas or the gas filter is starting to clog up.
