    Only way to get that information is from a dealership, or ebay. You'll need the Technical Assistance Manual, which can cost you up to $300 depending on where you shop. The poor mans way is to make a detailed diagram of where pieces are connected to your engine. Serialize every part you disconnect. You'll start by removing the air intake manifold, from the filter, to the inlet plenum. That'll take about 2 hours, and remember that your car uses the Metric System. A 12mm, 14mm socket and extension will get off everything you need. Count your bolts, and store them away from the work area. The rest is just like any other tune-up. Remove the spark plugs, clean inside the voided area, and replace plugs and wires. You'll also need a new Gasket for the Intake Manifold, it's metal, but it's only $15 or so. It's also a good idea to take a look at your fuel injectors while you're there, and to remove and replace the gasket and boot seals under the valve cover (which is the piece that forms the wells your spark plugs are in). Put everything back just the way you found it. Remember the firing order is (from Left to Right) 5,2,1,4,3,6.

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:

Spark Plug Replacement


I changed my spark plugs and wires myself two days ago after a quote of around $550 from a local repair shop with welcomed success. It's really high because of the time it takes to do this job. I took my time and did it in about 5 hrs. The answer given for the website is a great source and helped me through a very tedious process. My best advice in addition to that is to have some 1" tape (i used flourescent green for visibility) and a sharpie and mark EVERY STINKING WIRE, HARNESS, PLUGS AND HOSES. Also it helps to make a small diagram of the bolt patterns and varoius lengths and placement of each. I started with numbering the bolts and lettering the wires and harnesses to combat confusion. I hope this helps anyone taking on this hideous task.
