wow i would be terrified if mine idled that low.....usually it just stalls out on me around 600 rpm

 

hmmm i dont know, thanks for the help and info guys. Im gonna take it back on tuesday and its either going to get fixed or im gonna go higher up on the ladder.

 

just out of curiosity what RPM does the fuel cut happen at the other end of the scale ?

 

The engine only cranks at 200-250 rpm. Your gauge has got to be off or something.

 

not sure what you mean by fuel cut? when cold it will idle slightly above 1000 then when warm it drops down to about 200-300

 

/\ when you floor it and keep your foot down till the fuel cut kicks in - it should read about 9500 rpm on the guage (which in reality is 9000 rpm).....

 

when cold my car will idle at 2000 then eventually drop to 1000-900.



i think my car is the normal one. this dealership is fucked up, i would be screaming bloody murder if they released my car back to me with nothing wrong. in fact, i know my dealership wouldnt ever do that to me, because they know me and know they'd have to take a bite out of such a large **** sandwich everyone would stare and gasp.

 

not sure ill test that sometime tonight and let you know

 

does you car shake really bad when idle? My car shakes if idle is any were nere 600. I couldnt imagine 200. Something must be wrong with your Tech

 

The fuel tables only go down to 500.
The idle control starts at 250.
You could effectively keep the car from even starting by just setting the rev limit to 250.
So, I think there is something else going on here.

 

no, car does not shake or vibrate at all really, i cant really tell its running when its warmed up and at idle

 

/\ i was thinking the whole scale was out
ie if reading 200 when it should be 800
at fuel cut it may only read 9000 instead of 9500 .

 

im not real knowledgeable about this type thing but that makes since to me, but why wouldnt the tech catch it

 

also is the scale stored in the ECU? is that what controls it because they reflashed it last week

 

/\ and the problem started after they reflashed it ?

 

ok the fuel cut is at 9000, and no the flash was a step to try and fix the problem. The problem was there before the flash

 

ok - it should be at 9500 . So it seems your whole guage is reading 5-600 low across the board .

 

i think the needle may just need adjusting..

 

/\ yes give it a tweak to the right - LOL

 

really?? something that simple?

 

because they are lying to you.

 

BINGO! Bad dealerships FTL.

kevin.

 

ok so an update on my car situation in case someone wants to know. The dealership had it all day today and they have narrowed it down and they believe the problem is the PCM. They are doing some more tests tomorrow to make sure. They quoted me 1200 for a re-manufactured PCM from mazda

 

year and miles? they have ruled out the CAN controller for the dashboard?

 

it is an 04 with about 87000. They said that they had ruled it out and they also call the higher up tech guys at mazda and they also confirmed the situation and that it has happened in about 15, of the 04 RX8's. They got 3 codes, random misfire, throttle position sensor, and a throttle control position sensor i believe. ( not 100% sure on that last one but it was something with the throttle pedal).
