"Fuel system too lean at idle". It's an air/fuel ratio that is not correct, possibly a vacuum leak somewhere. Or a leaky exhaust pipe. Could be related to intake manifold gasket. Somewhere, air is getting into the engine.

I suggest taking it back to the dealer under warranty. I think Hyundai is 10yr./100k for the original owner. 5yr./50k if not. Ask first if covered, and ask why not id not covered.

more than likely you have a bad oil control valve if in fact you have an 06 sonata. They are chain driven engines... You can ohm out the valve and get a good reading even when the valve is bad. Pull it out and check to see if it is clogged, if it is thats more likely your problem. If it is clean, go ahead and replace the valve. Hyundai calls them the oil control valve (OCV) and usually located on the head close the the variable valve sprocket.
