Sparky Posted September 11, 2016 Share Posted September 11, 2016 I think mine sits around 600 with no air con on.. Does it sound rough / rough idle at all? Any shaking through the car? Lucky man / lady by the way, 2014 model Quote Link to comment Share on other sites More sharing options...
BLK ISF Posted September 12, 2016 Share Posted September 12, 2016 Was going to ask the same thing. Any kind of idle surge, fluctuations in your revs vs dropping to 500 and remaining constant. Possible vacuum leak? On my old WRX, i had idle surge, ended up being a blown head gasket but im sure no such thing would happen to such a new ISF.

Sparky Posted September 12, 2016 Share Posted September 12, 2016 I checked yesterday, sits at 500rpm at normal idle, and 600rpm with aircon on. So you are all sweet!! Unless we both are faulty haha! Quote Link to comment Share on other sites More sharing options...
ich1ban Posted September 12, 2016 Share Posted September 12, 2016 Yep mine sits at the same on idle, fairly sure that's normal. Quote Link to comment Share on other sites More sharing options...
hhao Posted September 13, 2016 Author Share Posted September 13, 2016 i went to dealer for normal service yesterday, and have this issue checked. mechanic cleaned the throttle , there were some carbon stuck there, now the idle revs comes to 600 rpm, everything is fine by the way, mechanic explained that maybe my car had been sit in my car park for too long to have the carbon built up.

Lucky man / lady by the way, 2014 model no shaking, have the car checked, problem cause by carbon built in throttle, everyhing is all good now. im a man by the way Quote Link to comment Share on other sites More sharing options...
Sciflyer Posted October 10, 2016 Share Posted October 10, 2016 This is standard for the ISF it seems, it is not a fault. I suspect it may be for fuel economy/emissions reasons, to set the idle rpm as low as possible. I agree, in reality it is too low and a bit annoying but you can overcome it by turning on any source of electrical drain such as headlights/sidelights, window demister, A/C, etc... or put it in Neutral :) Quote Link to comment Share on other sites More sharing options...
2bling Posted October 10, 2016 Share Posted October 10, 2016 Have a look on utube most idle at 700 mine sits at 700, if it isn't a problem don't worry go out and flog the date out of it.This is good advice trust me i am a mechanic cheers.

ilv1004s Posted October 11, 2016 Share Posted October 11, 2016 500-600 rpm depending on a/c on or off is normal not to worry Quote Link to comment Share on other sites More sharing options...
Peter G Posted October 27, 2016 Share Posted October 27, 2016 My MY11 is the same. 500rpm without the aircon on. Quote Link to comment Share on other sites More sharing options...
