What all can cause my 1999 ford Mustang srs to miss?

Bad plugs, bad wires are the easiest to check. I developed a miss on an AMG supercharged V8 engine in the number 8 cylinder. That turned out to be a busted ringland, oil was getting into the combustion chamber and wetting down the spark plugs. That's a rebuild or engine replacement when that happens.
