mdjdc Posted April 10, 2013 Share Posted April 10, 2013 I have a friend whose daughter has a 90 loyale and it seems to have a constant high idle. he says that the idle stays around 2000 all the time. I am going to look at it tomorrow and just wanted some suggestions as to possible causes. Any direction will help me gat it fixed faster.

man on the moon Posted April 10, 2013 Share Posted April 10, 2013 Vacuum lines? Quote Link to comment Share on other sites More sharing options...
tdodge41 Posted April 10, 2013 Share Posted April 10, 2013 Hey Mdjdc, I would check the vacuum lines first maybe? I know my 85 Brat has a high idle as well that doesn't really seem remedied by the idle screw, I am working on replacing all my vacuum lines (as soon as I can identify all of them). Ah the joys of learning. Quote Link to comment Share on other sites More sharing options...
mikaleda Posted April 10, 2013 Share Posted April 10, 2013 (edited) I would start by checking for codes. coolant temp sensor, iac, vaccume leaks, and sticking or improperly adjusted throttle cable are possible causes.

Ah the joys of learning. I would stay away from that screw. Idle is computer controlled. I have heard about cleaning IAC valve. Good luck, Sam Quote Link to comment Share on other sites More sharing options...
rain_man_rich Posted April 10, 2013 Share Posted April 10, 2013 What mikaleda said plus clean the throttle body if it looks dirty. Quote Link to comment Share on other sites More sharing options...
mdjdc Posted April 10, 2013 Author Share Posted April 10, 2013 Thanks guys. Right now the coumputer is not throwing any codes. I will look at all the obvious things first and I will clean the throttle body. Quote Link to comment Share on other sites More sharing options...
mdjdc Posted April 12, 2013 Author Share Posted April 12, 2013 Thanks guys. Turned out that he had a cracked intake boot and the IAC was sticking. Replaced both of those and now the car idles at 1000 rpm. 1 Quote Link to comment Share on other sites More sharing options...
