#30 of 79 Re: 93' Mitsubishi diamante start then wont start [misty25] by ss4ela Feb 09, 2007 (7:26 pm)
Replying to: misty25 (Jan 05, 2007 8:11 am) I had a similar prob w/my 92 LS, except mine would run 4 about the first 45 min (when cold) in the am, then stall,would not start until it sat and cooled 4 about 15 min. then would run 4 another 5-10 min.Mine turned out 2 be the ECU.(Engine Control Unit). Found 1 online for 425.00(joined Planet Salvage). But yours sounds like a possible fuel pump problem. As an auto tech, I have seen this symptom more than a few times leading to the electic fuel pump. Pump is universal, so it is fairly inexpensive,but is located in fuel tank,high labor. easy 2 diag.-just have mech. friend install fuel pressure guage, make sure its up 2 spec.,& make sure it holds steady pressure w/key on. if not,replace. Hope this helps,E

Replying to: tlye (Jul 11, 2006 2:04 pm) I had antifreeze leakage on the driver's side carpet, odor and residue on inside of the windows -fog. (2002, 6 cyl., 3.5 liter).   The Mitsubishi Service "greeter" told me the the heater core was on the passenger side and that the dampness under the driver's feet might be from a hole - going through water!   I had a mechanic who fixed only heater cores replace it. He told me he had to remove the entire dash and huge number of fasteners. Replies to this message: diamoney (Feb 22, 2007 8:20 am)

#33 of 79 Satelite Radio by diamoney Feb 22, 2007 (12:48 pm)
I have a 02 Diamante, anyone ever install an XM/Sirius radio in their rig? If not, know anyone who may have taken on this task? My question is this, what hardward did you need and where did you install it?
#34 of 79 Krazy 1997 Mitsubishi Transmission by ldelaney Feb 23, 2007 (11:14 pm)
Just before I stop, the transmission does a hard downshift and sometimes lurches forward. Major transmission company overhauled but still does same thing only not as bad. They reflash the tranny, works fine until shut off, then does same thing when restarted. What gives?

Replying to: diamoney (Sep 05, 2006 12:57 pm) that is due to worn lower "pillow" bushings in the rear knuckle. they can be replaced seperatly.
#36 of 79 Need maintenance schedule by crobertson Apr 09, 2007 (11:12 am)
I recently bought a 03 Diamante (which I dearly love, so far). I had to get the owners manual myself, but it doesn't give the recommended mileage for maintenance, only what to do and how to do it. would someone happen to have  that info, it surely wouldn't be very much. I've already tried the maintenance program from edmunds, they don't have any info. I sure would appreciate it!!
#37 of 79 Re: Check Engine Light for Diamante 2002 [88oldscutlassc] by diamoney Jun 01, 2007 (11:29 am)
Replying to: 88oldscutlassc (Dec 24, 2006 6:34 pm) Heater core was between 400-500 bucks.. I did the rotors on all four, and replaced the pads in the back for under $200.00, and about 2 hrs..   In response to my previous issue, the rear nuckle bushings were replaced and solved my problem.. apparently it is pretty standard on these cars.. $400.00 at the stealership.
#38 of 79 Idling. by diamoney Jun 01, 2007 (11:33 am)
Question.. As the seasonal temp rises my car starts to act up a bit. In stop/go traffic on a warm/hot day, my cars idle will slow almost to a stall, then jump back up.. If I put it in neutral, it stays fairly steady, then I pop it back in gear when I need to advance. I have a little less of an issue if I switch the A/C off, but then I sweat my balls off..   Any suggestions?? I was thinking I should replace the plugs.. I have at least 60K on them.. If that is a good idea, how do I get to these.. I can't seem to see them when I pop the hood..   suggestions??
