wkdtime Posted December 11, 2006 Share Posted December 11, 2006 Firstly, check for fault codes bud, and whilst your there carry out a diagnostic check of the Lambda sensor (Oxygen sensor). Make sure you have no vac leaks or any kinked vac lines, it may be wise to give the Idle Speed control valve a clean aswell. See below for Component location, Lambda sensor check, Fault codes check. http://www.mkivsupra.net/vbb/showthread.php?t=35920 http://www.mkivsupra.net/vbb/showthread.php?t=35925 http://www.mkivsupra.net/vbb/showthread.php?t=35940 Quote Link to comment Share on other sites More sharing options...
_Rob_ Posted June 7, 2007 Share Posted June 7, 2007 Matt, did you solve this? Mines done it before, I gave the idle control valve a clean and it solved it. However, its just started doing it again. Wondering what youre solution was. Quote Link to comment Share on other sites More sharing options...
