After doing some research there is a high probability that one of the coil packs is bad and isn't making a good connection after enough heat is transmitted between the coil pack and the spark plug. Heat expansion will cause the coil pack to not create the proper amount of voltage and spark. You might also find an improper gap on a spark plug increased voltage being required to create a spark in the chamber.

Not a valid trouble code for 2003 Hyundai Accent but it is valid for 2004 Mazda RX-8. You don't replace ANYTHING until you find out why the mixture is too lean. This could be caused by at least 20 different things. If your shop doesn't know how to diagnose the root problem, find a shop that does. If you start throwing parts at this without diagnosing, you could easily drop $1,000 and still not fix the problem.
