I have an 09 X 6 speed and it's only got around 5700 miles and you know how when you are at a stop and it idles at around 900 rpms. Well every once in a while it will start to idle at around 600 rpms.
I took it to the dealer and I couldn't replicate it.

Is this bad? Everytime it starts to idle at 600 rpms I treat it as a stall and I turn it off and restart.

Mine has done this a couple of times but has never stalled. It would always recover too, like from a dead stop and the light changes kind of thing. Not too sure what it is and it only happens once in a while.

Don't mean to be an A**, but is your A/C on, or even the fan?

azrwilkinson

Mine acts up w/ without a/c, but that doesnt mean it needed it for cooling. Good thought!

your's idles at 900 normally?
mine idles at around 600 normally.
I'm pretty sure it might have something to do with the eco system built into it but i can't find shit on it in the manual so i have no idea.

Mine noramlly idles at around 600. Does it act like it's idling rough? I would be more curious as to why it idles around 900 personally, if it is idling there after it warms up anyway.

Mine has done this a couple of times too. I think its emissions related.

The first thing I would look for is a vacuum leak. High idle indicates that you have one. The normal idle speed is around 600-700 rpm. In your situation when the computer tries to idle it down then it wants to die. If you can't find a vacuum leak, I would check the EGR to see if it was sticking open a little.

I never use my A/C my doors are usually off and my side windows are always down. I cleaned all the mud out all the time. I think it's probably emissions.
