simonb 0 Posted April 8, 2006 If it's not the throttle cable then it can only be an air leak the size of Canada somwhere in the inlet pipework... Share this post Link to post Share on other sites
richsmells 2 Posted April 8, 2006 As usual, check the screw that holds the oil filler to the inlet manifold. If it's missing it will be letting unmetered air in. Share this post Link to post Share on other sites
kate205gti 4 Posted April 8, 2006 yeh mine did that when the screw was missing lol! check the top right hand side of the inlet mani for a blooming big hole might have to adjust the idle screw once uve plugged it but should be fine after that Share this post Link to post Share on other sites
