vw.classics 0 Posted October 2, 2012 Need some advice please guys... Car is currently running very sweet at present with the exception of intermittent high idles issues. It is occasionally idling at around 2000 rpm when warm and running and then will drop back down. Any obvious areas to check...could it be a split hose causing excessive air / fuel mixture?

davidwort 0 Posted October 3, 2012 have you read any of the 'idlde valve' or 'ISV'and related rough running/idling threads, sticking idle valves often cause this. Quote Share this post Link to post Share on other sites
