stalling is from MAP SENSOR or Throttle Posiotion Sensor. and the dash and lite issue is b/c ur head light switch is going bad.

lower wattage glow plugs will last longer than higher wattage ,also how long the timer is on for as well ,also the make ,a good bosch one will last for years ,a cheaper one made in china maybe two years max .

replace the charging relay

Headlights commonly only last a 350-400 hours. If you're not getting this, you might have a power problem OR are using lower quality bulbs.
I like to use Narva Artic Blues - they have a higher output and last longer. Also, most auto stores will provide a free replacement if they blow very quickly.
Check the fuse for your headlights - if it is incorrect change it and replace it with the correct fuse. Other than this, you may like to check the wiring - check all the connections are secure and that there are no shorts in the cable.
Hope this helps, Sherwin

i had the same prob last week and it turned out to be the fuel pump. easiest way to see if that is the prob unhook the fuel line before the fuel filter and turn key and see if the fuel pumps good if nothing then theres the prob.

If your catalytic converter is "below efficiency" or otherwise clogged, you will lose power as you drive and the vehicle heats. The more you drive the vehicle, the worse the problem will become. The exhaust can't escape properly through the catalytic converter, therefore your engine won't run properly. Your issues are related, and if you replace your catalytic converter they should go away.

Put some waterproof electrical grease (you can get at auto zone) on end of bulb before you put in in! The reason bulbs are blowing, is they are getting wet!

I've got a 2001 Elantra that "eats" headlights. Within the last five years, I've probably replaced both headlights 10-15 times. Last time I bought bulbs, the clerk at the Auto Zone recommended coating the connection points of the bulbs in electrical grease (which is different than regular grease). It's usually sold in small foil packages at the check-outs. Anyway, this seemed to prolong the life of the bulbs by 3-4 times. It's a cheap fix that didn't completely solved the problem, but sure cut down on the number of bulb replacements.

BCM needs replaced the cost is around 160.00
