Hello
I have recently acquired a Mitsubishi Montero io GDi (sometime known as a Pajero Panin I think). It's a fab car and I love it! It was first registered in 2001 in Spain, where it continues to reside. It has been suffering from rough running - possibly mis-firing, though I'm no expert so this is just a guess. The spark plugs were replaced 6 months ago which improved things at the time, but, whilst the car has hardly been used since, the problem seems to be coming back. It gets worse when the car warms up a bit and the problem is most noticeable when 'you put your foot down' or pull away in a gear slightly too high for the speed. It has 95,000km on the clock, so was thinking the next thing to try are the ignition coils? I examined these prior to the plugs being changed and they did seem to show signs of corrosion.

I would really appreciate some help here. I think I need to identify exactly which engine I have, if there is a part number for the ignition coils and where I might be able to find replacements?

Thank you kindly in advance,
Graham

Here is an image of an Australian Pajero Compliance(Data) Plate.

It shows the engine type in this specific model which, in this case, is a "6g74" v6.
Your Pajero i0 will probably have an engine number starting in "4G.."

It will be an inline 4 cylinder engine.

Your thread takes me back to about the year 2001, where I sold my one and only Pajero i0 out of all of the thousands of used/new cars that I sold over a 15 year career.

Memories.....

P.S. I appreciate the action that you took to relocate the thread to the correct place so quickly.

If you can correctly identify the engine in your car, I will do what I can to help identify parts.

Thank you so much for this - I will go and take a look now to see if I can find the details.

Delighted to hear this has brought back memories..! We love the car. It has bull bars and running plates - it was specced by a builder who used it to drive around his various sites. So it's small, chunky, and lots of fun. Just want to make sure we keep it going for as long as possible.🙂

Like yourself, I was impressed by the layout when I first saw one.

It was not a "hard sell".

The opposite, in fact.

For those interested, here is a 2006 Australian magazine article about the "4g9." series of engines.

As you correctly pointed out, it's a '4G93' engine - I'm so glad I've found this forum.!! Thank you also for the above link. I shall look forward to seeing what this reveals.
Thanks for all your input.

Hi Graham,

Can you provide some more information please?

I am assuming Left Hand Drive as it is in Spain?

Is it Auto/Manual?

Transaxle code "V5M21" suggests Manual?

From the Data Plate code "H66W" I am thinking Short Wheelbase?

Also from "H66W" 1.8litre engine?

Turbo or non-turbo?

Is there an additional Data Plate that you could photograph in addition to the one above in post #7?

If there is an extra plate, it would normally be next to/close to the other one.

I am hoping it might include month/year of manufacture.

An image of the whole car from the side/rear would help to include any distinguishing model badges.

An image of the top of the engine would also be very helpful.

Like some of the images in the magazine article I linked to.

A picture is worth a thousand words.....

I have found a catalogue:

Hello

Answering your questions as best I can:
Left Hand Drive, Manual, 1.8
I couldn't be certain, but I suspect it's short wheel base.
Here are some photos of our beloved car...

Thank you so much for all your time - so very much appreciated.
Best wishes,
Graham

This is great - thank you. The listing here mentions type H66W. The paperwork I have mentions H60W - will there be much difference?

 

[Leadfoot6]

It is certainly the Short Wheelbase model.

You threw me for a minute.

I went back to the parts catalogue.

On the left shows "H66W".....on the right shows "H60,70#"

I don't think this will present a problem.

Column 3 = "Model" ...................Column 5 = "Frame".

I am sorry the screenshot is such poor quality.

I do not know how to fix this.

I see that there is an online "help" facility.

You might be able to make use of this, as you will have the necessary identifying numbers in your images that they will probably ask for.

Of course, if this online "help" turns out to be no actual help, check in again, but from this point there is not much more I can do from this side of the world.

Good luck.

Thank you so much for all your help. I'll pursue this line in the hope I can find what I need. If this comes to nothing, I'll be straight back.
Very best wishes,
Graham

Although, I would not be too hasty in "putting all your chips on one number".

What other steps could you take to do some troubleshooting?

You might replace the coils, and find the trouble still persists.

Great, thank you. I've posted a question, so hopefully they'll get back to me - tomorrow perhaps.

Well, I'm afraid I'm really rather clueless when it comes to car mechanics, though I'm not incapable of learning and giving things a go. So, in trying to work out the problem I can only apply logical thought. I have assumed that, given that the car runs, albeit a little rough at times, that the main fuel system should be working. My next port of call was the ignition system. The plugs were replaced 6 months ago so the coils seem to me to be the next logical thing to try. When I inspected them, the contact points inside did look a little corroded - perhaps this is an indicator? I'm anticipating spending around £120UK to replace the coils - I'm confident I can fit these. If the problem continues beyond this, though, I fear I may be stuck. I expect I'll have neither the confidence nor the tooling to tackle anything more technical. I do think that £120 is low enough to give it a go...
Best wishes,
Graham
