stevec14 10 Posted June 15, 2013 Hi all Don't know if any one has had this problem on their Corrado G60 so i thought i'd post it up. On start up from cold engine would tick over at 1600 rpm and once warmed up would then fluctuate between 1200-1600 rpm approx. Thought it could be the ISV valve but on further inspection found a cable snapped off for the lamba probe(by plug) and also the micro switch for throttle park position not made on idle(bracket for switch had been bent?). When these problems were rectified started car up from cold tick over 1100 rpm approx then when warmed up drops to a nice steady 800rpm. Hope this helps Steve Quote Share this post Link to post Share on other sites
