Some time back I installed plugs in my truck and shortly afterwards it started a slight miss. I tracked it down to a new defective plug. These days you never know.
Have you also checked for intake leaks?
Unfortunately, there's several things that can cause the miss including distributor itself and/or emission parts. If you can have it diagnosed in a shop, that would be the easiest and fastest, otherwise, you just have to start eliminating.
