Here's a link to the issues associated with a P0174 code:
http://engine-codes.com/p0174_mitsubishi.html

There's a bit of a punch list of stuff that could be causing this code. If you have never changed the O2 sensors on this car that is where I would start; replace all of them. Get OEM exact replacements versus "universal" fit O2 sensors.
The Mass Airflow Sensor (MAF) may be dirty. There is specially formulated cleaner for removing any built up mung on the sensor.
The PCV system can be checked for proper flow. Replace the PCV and/or clean the system if there is no valve.
Bring the car in and have the injectors professionally cleaned.

You're probably in the neighborhood of 165-170K. If you've never done any preventive or regular maintenance then there could be a lot of issues with your car. The P0174 is a lean condition. It could be bogus inputs to the engine management computer (via bad O2 sensors and/or a dirty or bogus MAF sensor). It could be really dirty injectors because they've never been cleaned and if you've been filling up with non-top tier fuel (because you're saving 2 cents a gallon) then it's a sure bet the injectors are dirty. Running lean comes from air leaks into the manifold post MAF sensor. This could be from rotted vacuum hoses or cracked/broken vacuum fittings. There's just too many possibilities to be able to nail it down for sure. Use the link and the info there to start your trouble shooting.

Pull out the radio far enough to see the serial number and model number. Take that and the registration to the dealer who will give you the code you need.

You will need the code to unlock the radio. First you must leave the key in the ON position for one hour with the radio display on.
The radio will shut itself off, and next time you turn it on "code" will be displayed again.
To get your code you need to pull your radio out to read the serial number, then provide that to your dealer for decoding, or present a question here with the serial number and we can decode it for you and instruct you how to input it.

2001 montero sport xls sport horn on my alarm how do i stop it i pulled the fuse but it is still goint


You need to determine if it's the horn or the alarm. My Montero (not Sport) had 3 horns. All 3 of which go off w/ the Alarm, but only one is connected to the horn on the steering wheel. I could not make mine go off w/o pulling the relay under the hood.

My spring was bad in the steering wheel. I was able to bypass the wire using instructions that I actually found on a Mitsubishi Forum. Link below:

Horn keeps blowing fuse/shorted out



Removing airbag: disconnect battery for 30 minutes before proceeding -- sounds like you know the rest -- just proceed carefully. If the airbag didn't deploy when you punched it, you're not going to set it off easing it out.
