Crash Commander Posted February 20, 2012 Share Posted February 20, 2012 Hey guys, I have a problem with my 1.6 vtec aerodeck. Basically it will erratically idle between 1000 -2000 rpms when cold but settle down to 800 rpm when warm. I suspect the thermostat is on the way out, could this be the cause?Thanks Quote Link to comment Share on other sites More sharing options...
KiNK43 Posted February 20, 2012 Share Posted February 20, 2012 If it gets upto temp as normal then I don't think thermostat. Try cleaning the iacv. Maybe its choked up if high milage or mainly town driving Quote Link to comment Share on other sites More sharing options...
Crash Commander Posted February 20, 2012 Author Share Posted February 20, 2012 Well when I drive on the open road the temp needle goes down almost to the bottom. But having been told about the iacv valve that may be the culprit as well as my car has done 106.000 miles. Quote Link to comment Share on other sites More sharing options...
KiNK43 Posted February 20, 2012 Share Posted February 20, 2012 Well if temp drops dramatically on open road. Then you probably have got thermostat issue. But probably worth cleaning iacv as maintanence anyway. It's easy to get at and do. Quote Link to comment Share on other sites More sharing options...

civicturbo79 Posted February 21, 2012 Share Posted February 21, 2012 I would say thermosat . if its not right after that clean the iscv after that i would say air leak somewhere something like a split vacuum pipe . Rich. Quote Link to comment Share on other sites More sharing options...
