I looked up the task...they make it sound like a HUGE chore....but this is what it looks like and it runs for about $50-60 for it.

Why does the "service engine soon" light appear on

you have an issue with vehicle. could be anything from loose fuel cap to failed catalyst/ cat convertor, which is very expensive. you need to know the code number to get started with diagnosing issue. get your self a small hand hels scanner from your local friendly auto parts store and scan for codes. some part stores may even scan it for you for FREE. nissan dealer will charge you arm and your leg to look at it. our dealership charges 1hr of labor to look at "service engine soon" light and diagnose it no matter if it takes 5 minutes to figure out or 45 minutes you will pay 1hr of labor which could be around $100 big ones. so get a scanner which goes for around $60 and scan it your self and this way you have a scanner for future if the light comes on again for something else. that light can copme on for number of reasons.

2003 nissan altima airbag blinking. Engine is running rough. Plus check engine soon light is illiminated.

On most vehicles, the airbag light should come on for @6 seconds, and then go off if the system is working properly. If there is a fault or a problem in the system, the light will remain illuminated, or flash continuously. If the airbag light does not work properly, some vehicles have an audible tone that sounds indicating a problem with the airbag light system. When the light is on (or the tone is sounding), the airbag will NOT deploy, even in an accident. Most systems can only be diagnosed using a scanner designed for the airbag system, however some use flash codes to indicate the problem. The scanners at Auto Zone or the ones that sell for @ $50 will not access the airbag system, only the engine systems (check engine light).
This website gives you the procedure for diagnosing and resetting some systems without a scanner. Some vehicle manufacturers accommodate that (like Toyota, Lexus, Nissan, Infinity, Honda, Acura, Ford, Lincoln, Mazda & Mercury) and some require a scan tool.

Will not idle

Check the idle air control valve, if that goes bad the car will have a real weak or erratic idle.. Other things might be a clogged fuel filter or faulty fuel pump,or the throttle positioning sensor might be going haywire. hope this helps and good luck.

That code is not in my book, it is a dealer specific code. Go to Auto Zone or Advanced Auto, and they will have a book that has "dealer" codes in it.
