hoss1720 Posted January 6, 2010 Share Posted January 6, 2010 Guys,my disco has recently developed an anoying little niggle. On first starting from cold the engine runs fine for about 30 sec to 1 minute,then the idle drops off and sometimes but not all the time it will cut out.If it doesnt stop the power picks straight back up to the correct idle speed? The other day I pulled up at a junction and it stalled.I t started up straight away but began to rev up and down of its own accord for about 15 seconds and then cleared. The engine is fitted to an auto box and the only real problem ive had was the airflow sensor which I replaced about 18 months ago(none genuine part). I service it on a basis regular(oil and filters)and the plugs are the iridium tipped type. any obvious suggestions? Quote Link to comment Share on other sites More sharing options...
landy V8 Posted January 6, 2010 Share Posted January 6, 2010 could be the idle speed control valve Quote Link to comment Share on other sites More sharing options...
vougese39 Posted January 8, 2010 Share Posted January 8, 2010 get the ecu fault read first to see if there is a idle valve fault or another sensor or you have a air leak is it on gas? Quote Link to comment Share on other sites More sharing options...
