YOU ARE GOING TO HAVE A HARD TIME YOU ARE GOING TO HAVE TO TAKE OUT INTAKE MANIFOLD TO GET TO ALL DRIVERS SIDE PLUGS AND THE ONE ON THE PASSENGER SIDE GOOD LUCK

what kind of answer was that, is their anyone with brains out there

***the person is 100% right. I just had my brother in law change my plugs and wires, Auto body wanted to charge me 500.00 dollars, because of the difficulty

Go to www.monterosportonline.com and they will give you detail by detail including pics. Best of luck because there is a lot of work to do.

Yes correct the intake will have to come off , but i am trying to find out why there may have been sludge on the spark plugs is it normal because they are located in the valve cover or not?

Yes the plugs go thru the valve covers. if there is oil or sludge as you say on the outside of the plugs,you will ned to change the valve cover gaskets felpro's gasket set comes with new orings for each hole to prevent oil leaking thru onto the plugs.

This tune up isnt for the weekend oil change guy but you can do it if you take your time and have a good memory........theres alot of unbolting, wire harness unpluging and vacuum unplugging as well! ya might wanna take pics as ya go so everything goes back together correctly. Mark all the spark plug wires at the coil so ya know where they plug it at cause once its together ya cant tell who is who! The firing order is on the wrote on the intake.

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:)

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

Hello - I have a 1987 Montero/Raider. The turnsignal/hazard relay is on the drivers side underneath the dash. It simply unplugs/plugs in. It's not hard to get to. Use a flashlight. Mine was very inexpensive to replace.

All depends on what kind of spark plugs you have. It could either be 30,000 miles or 150,000 miles.

could be several reasons. most probable is plugs or/and wires. possible low fuel pressure. does the engine light come on? If not probably plugs and/or wires. Have fun installing them

If you dont know how to replace spark plugs I recomend you go to someone that does and have him show you because you might do more bad then good trying to change them for the first time.

If this still has the factory motor it should be either a 3.0 V6 or a 4 cyl. Both of them should have the freeze plugs located in the side of the block. It is identifiable by the circle shaped "cups" inserted into the side of the block.

first of all you have to consider several things. 1. what is the mileage? if you have high miles you will want to change the valve cover gaskets. The reason is you will need to remove the plenum to get to the plugs and you will want to do this right the first time. 2. change your plugs while you are in there. This is very easy to do. It looks intimidating but invest the time and you be surprised how easy it is. I just did the timing belt, guide, tensioner, hydraulic tensioner, water pump, valve cover gaskets, plugs and plug wires and fuel filter and my montero runs like new with 140,000 miles.

Although the 93 Dodge Stealth basic engine mechanicals are the same as one for a Montero, you would probably have to use different engine mounts and there may be a problem with how the engine mounts to the transmission. Then theres the possible problem of the engine computer for the Montero not working with the donor engine and the wiring harnesses not having the same plugs as the Stealth.

How do you replace the spark plugs on a Peugeot 307?

It could be one or two of several things...no spark to the plugs...no gas to the injectors...engine is out of time (the timing belt/chain has broken or is stretched, so it does not operate the valves correctly).

2 hours if your top notch technician. You have to remove the upper intake manifold before you get to them. And about 6 hours if you are not a top notch technician. Just remember to mark everything with a paint pen or marker of so sort, even take photos to try and help with putting the manifold back together.

If your Diamante is the Dohc 6 cyl. motor in it then you have to remove the entire intake manifold to replace the back 3 plugs I did it in about 4 hours with not many tools and I am a female. So it can be done.
