I had same problem and my repair shop just replaced a sensor in the tranny. Said it was a defect by Hyundai,but they won't recall it.

It is either a 2.4L 4 cylinder, or a 2.5L V6. I double checked with Hyundai and this is all they show to offer for 1999. If you are still unsure, check how many spark wires you have, 4 or 6, and this will tell you how many cylinders you have. Hope this helps.

"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.
