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.

From what I have read up, faulty ignition coils are a regular issue with 2002 model onwards. Also a broken PCV hose. Please check that

put a new rear O2 sensor and it fixed it. Only problem you might have is if you have an aftermarket downpipe. If it is Catless then you are going to need some type of tune, opensource, Cobb AP, etc.... Even if it is a high flow cat then you will still need a tune because it will throw a code 75% of the time. If your stock cat is still on then replace your rear O2 sensor and that should fix it. Could be something else but mine was the exact same problem.

Fuel trim too lean. Usually means vacuum leak. Look for crushed,broken or melted off vacuum hoses near intake manifold. Or an obvious hissing noise at a normal idle. If so replace or repair clear codes your done. If not obvious take carb cleaner spray with nozzle attached car running & go over all vacuum hoses,intake manifold,egr valve see if idle raises if so you found leak. Repair. Could also be bad oxygen sensor switching bad o2 sensor but rarely.
Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.
