When you originally took it in, did you ask them to diagnose the misfire? Or was the partial tune up in hopes of tixing it? Valve cover gasket will prevent the wires from going bad due to oil contamination, but will not solve a misfire.
Have this diagnised by some one (a shop) that is capable. "One guy says" is going to get expensive. Maybe it is a cap and rotor, but misfires can be caused from much more that tune up related problems. No one likes to pay for diagnosing, but it usually cheaper in the long run.
