Sorry, me not familiar with your model EG9.

 

But it looks to me like......your ECU got problem liao. Usually, when you switch on a/c, it should compensate it. Apparently, it's not happening.....

 

But what about if there's no a/c? How much is the normal idle rpm?

bro, check your A/F sensor & throttle body, they could be dirty

[Andy]

hey bro,the idling when a/c is off is ard700 plus to 800..

[Andy]

hey bro,how to check if is dirty??any recommend place to clean??

[Vtim]

you can DIY if you want to, else just bring to your regular mech to ask he to clean for you if you need to DIY, I have lobang for the STP can spray cleaner

[Saaber]

ask you mech to check the IACV...

[Orangie]

Could be idle too low

[Saaber]
