Default Re: Help to raise my AU 5.0 idle rpm

I think i know whats going on ..On the back of the bonnet it's got the idle speed an shows that when engine is cold it idles lower as the motor reaches temp the revs increase at idle, so it's only when engine is at normal operating temp that it sits on 750 rpm .cold temp under 105 f>625 -675rpm 650-700rpm an 750-800 rpm at normal operating temp
So 774 r p m when warm was pretty close to what I had when I checked it
