The big question here is this. Did you have a misfire BEFORE you did the work?
If the answer is no, you must look at "cause and effect" principle, which means that something you installed introduced that misfire.
For a 95, I prefer Champion Copper plugs, but I do not believe that the plugs (if properly gapped to .035, did you verify this on each plug before installing?) would be the cause.
Do you still have your old parts? If you do and if you didn't have a misfire before, I would start with replacing one old part at a time until you find the problem.
Keep us updated! This is not going to be hard to find.
