You must remove the aluminum Intake manifold ( upper & middle portion only ) to access the spark plugs. It's best left to a Professional Mechanic to do the job. The cost can vary. Look at atleast $400.00.. Just as a side note. The biggest hassle will be putting all those hoses & wire plugs you disconnected back in the right spot. The other is locating the proper bolts ( under all those hose & wires ) to remove the intake. Remember that this intake manifold only breathes air so no antifreeze BS to worry about. If you have the proper tools, patients & alot of time you can do it. I suggest perhaps taking some digital photos of the engine before you dig in - it will assist in getting some hoses back to the right spot ( label or color code hoses & wires first ) Good Luck ! And I will be doing this this weekend!
Just like the 1998 model !!! Really ... Have Fun it's MitsushiTTI
THE INTAKE MANIFOLD MUST BE REMOVED. I WAS QUOTED > $600 TO CHANGE PLUGS. I SOLD MINE, AS IT WAS TIME FOR A TIMING BELT AS WELL. ANOTHER $600.
It is a lengthy process that can be found at http://www.monterosportonline.com/diy-perf2.HTML. you have remove the intake manifold in order to replace the spark plugs or the spark plug wires. It's not a recommended task for unexperianced person.
Replacing spark plugs is pretty simple. Disconnect the battery, remove the cover and cables, remove the old spark plugs, put in the new spark plugs, put the cover and wires back on the spark plugs, and reconnect the battery.
Disconnect the battery cables, remove the spark plug cables and covers, and remove the old spark plugs. Next, put in the new spark plugs, attach the covers and spark plug cables and reconnect the battery cables.
I took mine to Tune-Up Masters and I was charged 159.99 because of the extra labor they had to do. On Montero Sports they have to remove the air intake to reach the other spark plugs.
you hve to pull the upper plentium.i just did it to my 02 3.0montero sport.its a pain, but not to bad if you kno wat your doing.
We have a 1995 Mitsubishi Montero (the people that brought your the fighter ZERO) and when it came time for a tune-up we couldn't get the plugs out. The car dealer here charged us over 500 dollars for a tune up and they had to remove the top part of the engine to reach the plugs, hence the large dollar value. We will NEVER own another Mitsubishi again! Good luck:)
possible bad fuel injector or bad coil.
The plugs are located under the intake plenum. This is a real job because it takes removing several bolts, wires and gaskets to get to them.

THe spark plugs are buried! IT is one of the frustrating designs of this car! It takes a couple of hours for a trained mechanic to do the work and even longer for the untrained. If you have the work done, get the best, most expensive spark plugs to replace them with. I wnt 60K on my first set and am 30K into my second set.
Cost a fortune...down in San Diego, Mits dealer gave me a quote of $450.00 to replace spark plugs and wires. Due to the reasoning that plugs and wires are inaccessible. The said price was quoted today...0430PM/04febCALIF
