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!

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..

Check Engine Light/Rough Idle

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!

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?

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 ...

Yeah, I did this a few months ago.. I thought it to be fairly easy.. I have a 2000, so there may be slight differences, but you just need to remove the caliper, and then pop off the rotor.. It maybe corroded so bad, that you have to pound it with a hammer, but it should pop right off.. I would only reccomend that you hammer it if you are replaceing them, if you intend to re-use them, you may want to be a little more delicate..
Try some brake cleaner and let it soak in for a min or two, or some WD, that works too..
