#45 of 82 2002 DIAMANTE - Having Alternator/Battery issues by mdfall Aug 12, 2007 (3:08 pm)
Hello all I have problems with my alternator. It is over charging the battery (which gets hot to a boiling point). My friend who is mechanic helped me replace the Alternator and the battery. I have both of them new. Now despite the new parts, the issue keeps coming back. I had to replace a second time the alternator and the shop agreed to give a new battery too. Today the mechanic told me that he needs to replace the Battery Relay (located in the fuse box).   On top of that, when I drive the car on the highway (60 mph), the car over heats. When it is stopped and on idle it looks normal. Are the issues related? Please help me come up with a solution. Thanks.

Replying to: diamoney (Jun 01, 2007 11:33 am) I have a 1997 Diamante with same issue (100k miles). Mine was carbon in the engine which I removed with SeaFoam which you can buy at Autozone for about $7. I sucked the SeaFoam up through the PCV Valve (pour in bowl and do this slowly, so engine wont die) while I jockeyed the throttle cable under hood (to keep engine from dying) to get all of it sucked up into engine intake. After all is sucked up, turn off car for 5-10 minutes and restart. It will smoke out the tailpiple like crazy for 10 mins (your neighboors might call fire dept from all the smoke!), but should smooth your idle if carbon related. My idle was smooth as glass not right after this cleaning, but after several days of driving. Seafoam is oxygen and catalytic conventer safe and will actually clean the converter, too. Your plugs should be of the 100K mile variety, but if cheap gas, carbon may be your issue. You may have also have EGR issues and check that valve and/or blockages, too. Decarboning intake and ports will help as well if you have EGR 403 code that is flagging/service engine light on. To change plug, you must remove the plenum, not as daunting a task as it seems, remove black plastic cover, bolts through plenum to block and you don't even have to remove airbox/flowmeter; leave attached and just pry/left up just out of way (but not too far too crack rubber hose from air box to plenum) to get to plugs, if truely foiled/need replacing. Replace plug wire at same time while you are in there. Good luck! Replies to this message: diamoney (Sep 15, 2007 11:00 am)

Replying to: jtkramer6 (Sep 14, 2007 8:40 pm) Thanks man.. I will give it a shot.. I actually went in and cleaned the throttle body, and valve.. It was a little tight in there, but I was able to smooth it out considerably... In regards to the plugs.. you were speaking about the spark-plugs correct? if so, can you clear it up for me.. I still am boggled about how to change them.. do i actually have to remove the upper to get at the rear plugs?? any help would be appreciated..
#51 of 82 Check Engine Light/Rough Idle by diaman94 Oct 12, 2007 (7:51 am)
I have a 1994 Diamante LS, not Calif. equipped. I recently purchased the vehicle used with 135000 miles on it. The vehicle has received regular maintenance in the past (The former owner is a close friend). Following a fluid check and simple cleaning of the engine compartment yesterday (11 Oct 07), the vehicle started fine, and ran smooth. Soon thereafter, however, it began to idle very roughly, and the check engine light came on. The vehicle still runs, but has experienced a noticeable loss of power and acceleration, and continues to idle poorly. During the cleaning operation, I did manage to spray some water under the hood, but not in any excessive quantity. I am at a loss to explain this sudden loss of power and rough idle/check engine warning. Any ideas you can provide would be greatly appreciated.   Thank You!

#52 of 82 Re: 2002 Diamante Relay Problems by jen0608 Oct 15, 2007 (6:43 am)
Replying to: diaman94 (Oct 12, 2007 7:51 am) I have a 2002 Diamante in good condition, but all of a sudden my Power Windows, Power Seats, and Sunroof all went at the same time. My brother told me it was the Relay but no Auto Parts shops have it. So I went to the dealer and they can't even find the part# thats given on the Relay. They want me to come in for a Diagnostic Test which costs $84, when the part is proabably $25. I need advice! Is this most likely the Relay that needs to be replaced? Can I get this without going in for a test? Replies to this message: cumbiamo (Oct 15, 2007 4:45 pm)

Replying to: jen0608 (Oct 15, 2007 6:43 am) I know this is obvious to some, but when I would take my Diamante in for repair new parts were always a fortune. My mechanic who closed shop use to find used parts from a Chicago warehouse and in one instance found it from a local junk yard... maybe worth checking in to ...
