RAugur33 Posted January 29, 2010 Share Posted January 29, 2010 Idle sits at 2,000 RPMs, cold or warm. Runs great otherwise. Any suggestions? Thanks Link to comment Share on other sites More sharing options...
suberdave Posted January 29, 2010 Share Posted January 29, 2010 IAC stuck, poss vacuume leak, if the idle is high, its getting extra air from somewhere... Link to comment Share on other sites More sharing options...
RAugur33 Posted January 31, 2010 Author Share Posted January 31, 2010 inspected and cleaned IAC solenoid; can't find a vacuum leak. Would a bad O2 sensor explain this? Link to comment Share on other sites More sharing options...
Gloyale Posted January 31, 2010 Share Posted January 31, 2010 Are you using a matching harness and intake? Early(90,91) Manual trans legacies use a different IAC with only 2 pins. Is it possible you have a missmatched harness/ECU/intake? Also have you double checked that the idle switch in the TPS is making contact when throttle is closed?

jrettenmayer Posted January 31, 2010 Share Posted January 31, 2010 I had the same problem, then realized that my throttle cable was too tight...maybe you just need to loosen it up? Link to comment Share on other sites More sharing options...
RAugur33 Posted February 2, 2010 Author Share Posted February 2, 2010 I will work through some of these suggestions and report back. Thanks. Link to comment Share on other sites More sharing options...
