Jonny Chee 0 Posted December 11, 2004 Hi, When I start up my car my idle is around 1000 rpm and it moves up and down. This usually sorts itself out within a few miles and returns to 750 rpm. Any ideas what could be causing this? Thanks. Quote Share this post Link to post Share on other sites
Henny 0 Posted December 13, 2004 your ISV is probably stuck... (Idle Stabilisation Valve) If you use the search for "ISV AND G60 AND idle" you'll find loads of stuff on here about them as it's a pretty common problem... 8) Quote Share this post Link to post Share on other sites
