crazyarab 6 Report post Posted January 7, 2010 Regardless if the car is warm or cold, idle is pulsing between 2-2.5k revs. It's not consistently happening but it's becoming more and more common now. Has anyone come across this issue before? Quote Share this post Link to post Share on other sites
_Alan_ 6 Report post Posted January 7, 2010 Atta, give your idle control valve (ICV) a clean out and make sure you hear the valve opening and closing as you tilt it from side to side. You should be able to hear it buzzing when you turn the car on before starting. Here's a link to some M20 idle info, might not be 100% relevant to your engine but nevertheless quite helpful: http://www.e30zone.net/modules.php?name=Fo...t=starting+warm P.S if your not already a member I highly recommend signing up - some good E30 info there..

ducatiss 1 Report post Posted January 7, 2010 Sorry - but does anyone do a search for posts on idle issues before posting a question? Seems to be the most commonly asked question on the board :-) Quote Share this post Link to post Share on other sites
e30ftw 410 Report post Posted January 7, 2010 2.5k ? At that high you must have a vacuum hose loose or a massive crack in the intake boot or something? Have you checked / replaced the hoses? Brake booster hose? Quote Share this post Link to post Share on other sites
