anyone know what would cause the commander to get - c air intake temps? and when reading the - temps the car will idle alittle rough?

 

If you mean "- - - - C" it means your Intake Air Sensor is busted or the wiring is broken. The Power FC defaults to a very rich condition to save your engine and so it runs crappy. Check the wiring and if it is OK, install a NEW IAT sensor and you will be fine.

 

thats what i was suspecting but wasn't sure it wont always read ------c it will come up on the screne as -30 thru -34c and then shoot back to the normal temps.

 

Mine did the same thing for about 3 months before it finally went belly up

 

Mine did the same thing...just replaced it a few weeks ago and no problems now. I think it might have actually been the cause of a lot of my little idle problems because it seems to run smoother now.

Replacing it doesn't even require removal of the upper intake manifold IF you have a single turbo and have removed the rat's nest. If you're still running the stock twins, you probably have to remove the UIM. I bought mine new from Mazdatrix for $62 bucks (you can probably find it cheaper elsewhere). You can check out THIS LINK for more info and pictures.

 

i have the sensor thats my project for this weekend.thanx for the help brian

 

i was able to just unbolt the manifold lift it up and replace it even with the rats nest. fixed all my problems smoothed out the idle cause it wasn't running rich.
