1996 chev c1500 4.3 vortec misfiring

Topic starter

theres a slight misfire i think. Had a fairly bad mis, changed the cap and rotor and it helped but its still there only not nearly as bad. I thought changing the cap and rotor would have fixed totally or not at all.  Maybe a coil or wire is bad too? I ws thinking i might try the fuel because its cheap and easy. Also no codes come up. I cant read live data.  Wondering what i should look at next. Thanks

Since the misfire situation got better by changing the electrical components, I assume that the issue is electric. I would change the wires/coils as well.
