Question about Hyundai Motor 1998 Sonata
I rebuilt the head and now when shifted into drive the idle drops and car stalls
You had alot apart to do your work, and I suspect the IAC motor has dirty passages, or EGR does.

1. Remove the dust cover from behind the bulb that needs replacement.
2. Unplug the bulb.
3. Taking note of the bulb orientation, unhook the bulb retaining clip from the tang that holds it in place.
4. Remove the bulb.
5. Install the new bulb in the same orientation and clip in place.
6. Reconnect the electrical connector to the bulb.
7. Reinstall the dust cover.
Alternatively, if the bulb is burned out and you have less than 60,000 miles, you should take the car to the dealer and let them do it for free for you.

I just had this problem on a 2001 elantra. I took it in for repair: the MAP (Manifold Absolute Pressure/ intake air temp) sensor was shot. $150 later it works just fine.

"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.

I used to have a 1999 Mitsubishi Eclipse with the same symptoms; my mechanic replaced the speed sensor ($65) and the problem went away. Take the car to auto zone and ask them to plug the computer, they normally do it free of charge. If it is the sensor, you may have to buy at the dealer.
