A tech 2 could tell you which cylinders are misfiring but if you dont have access to that i personally would start with new spark plugs and wires.

Ronn, do you have a scanner? Without being able to monitor the engine systems you are in the dark. Spark plugs and wires are always a good start especially if you don't know how old they are. Spend a few extra bucks on better wires. They make a big difference on these cars.

Most of the misfire issues we see on the forum are resolved with new plugs and wires. If they have not been changed in a while, or you don't know the history, you should start there.
