Well, since only the #1 cylender is misfiring, I would start with a basic tune up. Have them replace the spark plugs and wires. That should take care of the problem unless there is an injector issue. However, usually, that has an affect on more than one cylender.
For a 4 cylender, I can't imagine the cost would be more than 80 to 100 dollars for plugs and wires.
Let me know what you find.
