hey all, over the last few days i have been having probs with my s2, if im driving round town, say every 5th or 6th time i pull away and it starts to boost in 2nd gear (the odd time in 3rd or 4th), she is really hesitant, as if either shes misfiring or there is a boost leak. then all of a sudden shes fine, then 10 mins later she does it again


why ????????!!!!!!!!!!!!!!!!!!
