#459 of 1497 Diamante Future
Aug 11, 2001 (9:17 pm)
taurus2--As I interpret the line in Automobile Magazine, these are the "last waning days" of the current model run. The current model started in 1997 and is expected to run until 2004 or 2005, so Mitsubishi has done a mid model run "freshening" on the front and rear of the car. If the link is still there on this page, (upper left under Additional Resources) click it to see the video and hightlights of the 2002 Diamante.

Thanks a lot! I heard that the Mazda Millenia will be gone in 2003. I was just wondering with that line "last waning days," if the Diamante was goin to be retired soon. With all the new Technology in mid level luxury cars today it would be smart to remodel the Diamante in 2003 to keep in race with Lexus, Infiniti, Acura.

I'm Jack and I have 1995 Diamante LS with DOHC engine, currently my car has 81,000 miles.
I have experienced with the same problem as Michelle "mkc" has. I'm taking my car to the dealer tomorrow for the repair. I hope that it will not break my budget and dealer will not rip me off on the invoice.
Michelle would you send me email with answer what was the problem with your dying Diamante?
My email is jackper22yahoo.com
Thanks a lot in advance!
P.S. I'm happy that I have found this forum!
#462 of 1497 Diamante Technology
Aug 14, 2001 (8:26 pm)
What most Americans do not realize is that the Diamante in Japan and Australia does have a lot of the same modern technology as its competitors, including in-dash navagation, auto-stick transmission and gasoline direct injection (GDI). Since the Diamante is not sold through a separate dealer network like Toyota does with Lexus, Nissan does with Infiniti and Honda does with Acura, Mitsubishi has to keep the price point attractive and that means leaving out some of the more pricey stuff. Also, with the limited production capacity of the Australia plant, only about 10,000 Diamantes are available for us (US) so it isn't economical to have options that may only be bought by 10-20% of the buyers. On the other hand, I do hear that the 2002 Diamante will have a VR-X model added which will have a sport suspension and more horsepower along with some sporty styling.

Will e-mail you as well. Mine turned out to be the idle control motor had shorted out - "old age and mileage", they said.
With oil change (needed anyway) it came to $607.
#464 of 1497 2000 with "cupped" tires
Aug 15, 2001 (9:59 am)
I took my 2000 Diamante with 22,000 miles to the dealer to have a fog light replaced and to tell me why so much road noise.
They told me the road noise is caused by the tread on the tires on the outside being worn - I beleive they used the words cupped.
When I asked how this might happen the dealer said tire pressure or alignment. They offered to sell me new tires but this seems like a waste since the Goodyear GA have a lot of tread life left.
Why should I do?

I got your email. Thank You very much for your quick response. You really helped me out, coz I know what should I check to fix the problem I'm having right now with my Diamante.
I see your problem went away but it cost you $600 to get it done. Ouch!
Thanks again Michelle!
#466 of 1497 Jack's D. Idle Problem
Aug 16, 2001 (5:28 am)
Since your e-mail to me mentioned that your D would still idle, I would suspect it might not be an idle control motor. In my case, once the engine had warmed up, the car would die unless I kept my foot on the accelerator. When it was cold, there was no evidence of a problem.
Also, a drop in idle under load (from 1000 in neutral to 650-800 in drive) might indicate something like a vacuum leak, air/fuel mixture, spark, etc. some of which are controlled by the ECM using readings from the sensors. I think the MAP sensor is one specifically which adjusts air/fuel/spark based on engine load.
If you search the Web on Mitsubishi Trouble Codes, you should come across the instructions for using a voltmeter to probe the Data Link Connector near the fuse box (I found it at www.batauto.com/mitsu.html ). It also tells how to read the 12V pulses and then what these codes mean. Long pulses occur first, which represent the "10's" place, followed by short pulses, which are "1's". Then it repeats.
So if you get 1 long pulse followed by 3 short pulses, this translates to trouble code 13 and the lookup chart says this is Intake Air Temp Sensor Fault.
Multiple codes (they start with the lowest number and go up, so for example I got a 13, 25, 31) probably mean something else has failed.
Typically, the Check Engine Light comes on if there's a true sensor fault (but not always).
You mentioned your D is a '95 with 80-something K. How recently have you had the EFI system serviced (plugs, wires, fuel filter, fuel-injector cleaning)?
As a data point, my D now idles in park with no load around 650 rpm and in drive or park with A/C on at around 1000 rpm. Idle is steady with no significant fluctuations (although the park-idle seems a little low and I keep forgetting to check the under-hood sticker to see what spec is (it's an ES, which should be SOHC, I believe).
Mr. Vivona - any wisdom you can share on Jack's symptoms I'm sure would benefit all as well.
#467 of 1497 '99 Diamante - Front end shudder....
Aug 21, 2001 (11:37 am)
Looking for others that have experienced this particular problem when applying the brakes.
I have had this problem at 6,000 miles, 11,000 miles, and now again at 21,000 miles.
Would like to know if there are any fixes out there that work, for longer than 10K miles. Also, does anyone know any contacts at Mitsubishi to call about this. I have called dealers and customer relations only to get told 'no problems'.
Thanks in advance.

Mitsubishi had tried different rotors on the Diamante (pre 5/99, 5-6/99, and post 6/99)but had no remedy to warped rotors. Exert care when installing them, or when changing tires (see Diamonds and pearls by Mr. Vivona) may help new aftermarket rotors last longer.
Instead of going back and forth with Mitsubishi about this issue, I proactively replaced my original rotors (which indeed got warped) with Beck/Arnley rotors that can be ordered at NAPA auto parts or Kragen for less than $200.00 a pair, tax included. Installing them is a snap, it took me 30 minutes for both.
If you follow Mr. Vivona's directions, they should not give you any problems in the future. Stay away from manufacturer's rotors, my Mitsubishi service advisor told me so. IMO $200.00 is a small price to pay for peace of mind, and the unnecessary aggravation for dealing with the manufacturer. Hope this will help.
