GreenVTi991 Posted January 18, 2012 Share Posted January 18, 2012 Hello again! When I come to a stand at a set of lights, handbrake on and in neutral, my Civic initially idles at about 1500rpm, then drops to just over 1000. If I'm stopped long enough it'll go to normal 800. Am I making a big deal out of nowt or is there something to check?Ta very much! Quote Link to comment Share on other sites More sharing options...

My Dad had this on his DC5, especially if the car wasn't used for a week.harVTEC Quote Link to comment Share on other sites More sharing options...
supertwisted Posted April 14, 2012 Share Posted April 14, 2012 Did you get anywhere with this? Mine does the same even when warmed up, its on my list of things to fix but not gotten round to it yet. Quote Link to comment Share on other sites More sharing options...
GreenVTi991 Posted April 18, 2012 Author Share Posted April 18, 2012 Yes i took the idle control valve off and cleaned it. It was black and the strainer was covered in soot. Put it back on and it has made little difference Quote Link to comment Share on other sites More sharing options...

supertwisted Posted April 18, 2012 Share Posted April 18, 2012 I was about to get a new thermostat, however I think it might just be overcooling in my case. After some experimentation, pootling around town it gets up to temp fine and the revs do drop down when on idle. But a sustained cruise at speed seems to be ramming so much air through the rad that the temp is dropping too far and as soon as you come to a halt the autochoke is back on again.Might trial blocking off the rad as others have had some success.
