CorradoVR6-Turbo 0 Posted August 23, 2009 sounds like the air bleed screw for idle mate. Quote Share this post Link to post Share on other sites
CazzaVR 0 Posted August 24, 2009 It sure is. Let the car idle, and adjust the screw so the idle speed is around 950rpm ;) Quote Share this post Link to post Share on other sites
aide 0 Posted August 24, 2009 if you're planning on messing with the idle screw then you'll need to do it whilst monitoring the fuel mixture also. Quote Share this post Link to post Share on other sites
bad-vw-boy 0 Posted August 24, 2009 How can you measure the fuel mixture ? Quote Share this post Link to post Share on other sites
aide 0 Posted August 24, 2009 you'll need an exhaust gas analyser is there actually a problem?! if ur not sure what your doing i'd take it to a garage for 5 mins rather than fiddling with it urself :salute: Quote Share this post Link to post Share on other sites
