ok so i am pretty new to the forum, i have been reading a lot for months now but just joined. I have searched the forum but cant find anyone else with this problem. My car idles at 200, the idle is not rough or jerky its just extremely low idle. I took my car to Mazda a couple of times but they cannot figure out what it is, i have changed wires, and plugs. Any one got any ideas???

 

It should idle around 800 once up to operational temp. I'm at a loss why it would idle that low, but my experience is that when it idles that low, it becomes unnervingly rough. Someone more knowledgeable than myself will chime in soon.

 

if this is really happening the cause would have to be in the throttle body or control of it. i doubt i tho since there are many ways to verify throttle control or throttle body issues with their equipment. so then its either a reporting issue or a gauge issue. which they should also be able to see when its hooked up.

 

yea exactly you would think that if it idle that low that it would be extremely rough but its not, it is smooth and drives just fine

 

damn, I would figure the car would stall out before it got down to 200 RPM

 

Heck it would die out if it's under 600rpm...

 

never stalled once on me, and i have had the car for over a year now

 

let me ask you a question actually. have they verified it is idling at 200? by that i mean they plugged it in to their comp and said " yep it is idling at that speed thats weird lets take a look at it" or have they merely taken it into the back then returned it to you and said "well we cant find anything wrong"?

 

hmmm not really sure actually, i presented the problem and then they have looked at it 4 times now but i just assumed that they would actually verify that it was in fact idling at 200, i didnt think that they would actually just take my word for it

 

yeah you need to get that straight with them first....

 

good thought, like i said i just assumed that they would verify that first thing. Ill mention that to them, i think im gonna take it back again.

 

Its gotta be a gauge not functioning properly. 200 RPM idle? No way..

 

i'm guessing high resistance in the sending wire to the cluster. if not the cluster itself.

PCM would be going nuts if it was seeing 200rpms tho so im thinking a cluster problem.

im going to say its a gauge problem. no way will the engine stay on at that rpm.

 

so i just got back from the dealership and they said that the cluster was fine no problems

 

okay so they verified idle at 200 with their machine and said there were no problems?

 

Thats what they told me, but im taking it back tuesday and they are supposed to keep it for a couple of days or until they find the problem. im just stumped about what it could be

 

wow they are giving you a huge brushoff.

kevin.

 

yea tell me about it. If they dont find out what the problem is next week then im gonna start being pretty straight forward and demand that something be done about it, because i mean it is a problem with my car and its not like an invisible problem and that is how they are treating it. they are acting like its nothing when in fact the car should not even be running at that low idle

 

words to live by: no results, escalate.

there's tons of people above the people at the dealer, and part of there job description is to make sure your car is 100% diagnosed and repaired.

kevin.

 

exactly. so if nothing gets done on tuesday or wednesday then im going up a notch

 

just out of curiosity, i saw that your avatar says mazda tech, so i was wondering how do i go about talking to people above the dealership if it comes to that??

 

they are lying if they had actually hooked it up they would have found whatever the problem is. so that means they didnt even hook it up. they got busy and didnt do anything and are covering their asses.

 

you ask to speak to the head of the department.

 

just ask, you could specifically ask for the contact info of the regional rep/ regional service manager or called MNAO corporate.
