maerijn Posted August 7, 2017 Share Posted August 7, 2017 (edited) Hi guys, I've got an EP81 with a glanza 4EFTE swapped into it, currently trying to fix a high idle problem. The car passed my countries MOT a while ago and emissions werent too high, also it is doing about 15KM/L so its running pretty good. I've been trying to find the source of this problem for a while now and already did: -replace PN 17630-11050 idle control valve, since the circular spring inside mine was broken-cleaned the throttle body, replaced seals, and set throttle position sensor, idle screw is all the way in-set igntion to 10' before TDC-searched for vacuum leaks, I found a tiny leak at an injector seal so I went out and replaced them all.-cleaned map sensor-replaced ECU water temp sensor-replaced lambda sensor However I am still stuck at around 1500 RPM idle. I was reading the parts catalog and spotted this second idle control valve which I think I dont have on my engine, it seems to go between a tube on the back of the manifold and then to the throttle body. Can anyone tell me what this is and if I should have it? Edited August 7, 2017 by maerijn Quote Link to post Share on other sites
TrisK Posted August 7, 2017 Share Posted August 7, 2017 that is for the power steering, so it raises the idle slightly when you lock it right over Quote Link to post Share on other sites
maerijn Posted August 7, 2017 Author Share Posted August 7, 2017 that is for the power steering, so it raises the idle slightly when you lock it right over Thinking now this might be the answer! Could it be this valve is usually closed and opens to raise idle when steering? I've currently have this tube uninterrupted so it could be causing high idle all the time!

maerijn Posted August 7, 2017 Author Share Posted August 7, 2017 You sir, are a hero, I blanked it of instead of running the tube and now my idle sits perfectly at 700 rpm! Quote Link to post Share on other sites
