vagingit.co.uk 0 Posted August 30, 2015 Report Share Posted August 30, 2015 My 1992 Corrado VR6 has an annoying high idle issue. It will idle at around 1200rpm. Sometimes, it idles fine, but 90% of the time sits there at 1200 rpm. Any ideas what could cause this? I have read that there is an idle speed screw on the throttle body, but I can't find it. Does anyone know the location of it please, if it exists? Thanks Link to post Share on other sites
