mr_K Posted July 15, 2016 Share Posted July 15, 2016 (edited) My glanza is having really bad low idle problems,In traffic when im stationary the cooling fan will kick on and then suddenly my revs bounce all the way down to 100rpm and back upto 800rpm, it evens stalls when its sitting in slow moving traffic.I dont know whats causing this problem,Ive uploaded a video and have a look at how low the idle drops.I purposly switched on all electronics so that you get an idea of it.The handbrake light dims and as i rev the engine i can see it getting brighter and back to dim when idle drops.Can it be a battery,alternator problem or a idle control valve?https://youtu.be/PDZyjsEx4zEThanks Edited July 15, 2016 by mr_K Quote Link to post Share on other sites
triple j Posted July 15, 2016 Share Posted July 15, 2016 (edited) Seems like alternator or could be a bad earth,chek battery with a meter to see if u are getting a good charge and maybe clean your earths. Edited July 15, 2016 by triple j Quote Link to post Share on other sites
patman Posted July 15, 2016 Share Posted July 15, 2016 This may not of caused the issue but I remember one time I forgot to put the pipe on from the inlet manifold to pcv valve and it done what's happening in the video Quote Link to post Share on other sites
