You had alot apart to do your work, and I suspect the IAC motor has dirty passages, or EGR does.

Answer
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.

SOURCE: hyundai elantra stalls loss of power while

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.

SOURCE: Hyundai Sonata 2006 - Check Engine light came on.

"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.

SOURCE: My RPM meter is not working...it's always on 0.

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.

I got 1994 toyota andf it stall when i turn on anything like blinkers or headlight and when i put it in gear. Its a five speeed v-6 but it starts right up and idles but if i hit brake it sounds likeit


ok , i guess you are saying the engine stalls when I use heavy electrical loads (like head lamps or brakes or even blinkers)
and when you shift from park to drive.
ok , if the engine RPM is 800 before the stall, then that is a total loss
of engine power with lost of idle controls.

The big load is in DRIVE on automatics huge going to DRIVE.

if battery voltage (yes, a 10 buck walfart meter works) can see 13.3 to 15vdc idling at 800 or more RPm.
the Alternator does not work below 800 so , dont expect it to.

so, if rpm in park is below 800 then we fix that first, see why?
if idle drops below 800 this is caused buy many things.
one vital fact missing is you didnt say, if I drive it like a stole it.
that is aggressive right foot. , do you have full engine power, now?
ignoring stalls. (see my drift there, "is engine power good;?)

battery volts above 13.3vdc.
idle at 800 and stalls in DRIVE (shifted)
  • low fuel pressure.
  • never ever tuned up this decade, with all spark parts bad.
  • ISC stuck( idle speed controller (it lets in more air , in DRIVE)
  • low engine compression.
  • other complex ,fueling issues, (ask) and lots of tests. (ask)
if no tachmeter in car or tool box, repairs get dicey.
hard,
it takes tools to diagnose and fix cars.
go tools? or willing to buy them
if not,? get it serviced.

Fixed egr vac sys on 98 hyundai sonata 3.0 v6 now engine runs rough


It sounds like a vacuum problem is keeping the EGR valve open causing the other sensors to read this and more fuel would be injected by the ECM. u may of gotten an egr code but the problem is not the valve itself.
