Runs But seem to act like it wants to cut off on 1994 Dodge Ram 1500

I have a 1994 dodge ram v8 it starts up great but seems to want to cut off I changed the spark plugs and wires got a new Z-BWD series Cap(C274Z) for it but it seem to want to cut off when I give it gas and it will not pick up speed I have no leaks of any kind and 17000 miles on it
