Rpm Idle Speed Without Aircon On?

[Blacky]

Hey just wondering what others cars idle at without aircon ON?

Mine runs at 500 rpm which I always think is a little low but just wondering if this is normal. Doesn't seem to faze the car but sometimes I think it is a little rough so low.

They tell me that the mixture is very lean at idle to reduce fuel consumption.

Mine is a little rough and variable in idle speed as well.

Yes, that is kind of what I was thinking also. That is had to do with low fuel consumption etc.

Cheers for the feedback

Mine's the same.

I was sitting at the lights thinking that my idle was a bit low and rough. Seems wrong to be so low but the car seems to adapt to it

Completely normal. Mine did it from 0km's brand new. There is a thread on it somewhere. Next time if you have your air-con off and it's idling @ 500RPM's, try flicking the headlight's on, even just the park light (one notch). The RPM's will jump to about 750RPM's.

Seems like if no accessories are on then it idle's at a low 500RPM's.

mine sits on 800 idle

600 when in gear

Mine is sitting at between 700 and 750 at idle with air con on or off and in gear or in park - all with lights off I think but will check this tomorrow as it was about 5.20 pm so not 100% certain about the lights.

Interesting, tried again today and with lights off it drops to 500rpm and I see what you guys mean by saying it feels rough. With JoeZ at 700rpm it throbs nicely, at 500 I cannot hear the exhaust at all.
