#50 of 79 Re: Idling. [jtkramer6] by 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 79 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 79 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 ...

Replying to: zasranec (Oct 17, 2007 5:38 pm) 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..

#59 of 79 '03 Diamante Flooding Problem by pcpftw Jan 09, 2008 (5:59 am)
I have this issue where my plugs are flooding and i had it at a dealership for a whole day and they said they checked everything out and cannot figure out what's wrong with it. It has started a little rough since the dealership replaced the plugs the first time but after it starts, it runs fine no rough idling. I am using this as a "last-ditch-effort" to see if you guys might have any ideas of what the problem might be. If so please get back with me ASAP. I have spent over $600 to get this "fixed" but it still isn't obviously. So, please help!!
