Missing Slightly

Hey Guys;
I just bought a 93 sc 5 speed with 48k on it. It was stored in a garage mostly and driven occasionally. I have put about 3,500 miles on it and now at cruising speed you can feel it cutting out a little. It doesn't do it under power that I can tell and it has a slight miss at idle. I was thinking since it sat so much it might need a fuel filter. Any ideas or should I just have it scoped? Could this be caused by spark plugs?Also I read that using a shorter spark plug can help control detonation, is this true? If so what ones should I get? One more thing, I bought the car in philly and drove it back to portland oregon pretty much non-stop. I did change the oil before I left and again when I got home(3,000 miles). All your help is greatly appreciated!!!!
