Hey there, my ej20 turbo engine idles fast most of the time, some times it idles normally (700) but most the the time is round 1000/1100. It does it when warmed up and ive also fiddled witht the idle control valve and with it twisted round as far as it goes still a bit fast. runs rough when i unplug the idle control sensor, so must be ok.
Appreciate suggestions

If memory serves it something to do with a temp sensor (basically I think the car doesn't know what the temp is, so its hitting the cold/warm idle sequence). I have the same problem with one of my EJ22 NA cars. If the car sits for a while (30 minutes or so) without the battery in the idle is crazy for a while (no matter the temp of the car). Can anyone else verify?
