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?
