idle and stalling issue

  1. #1
    hi, i know lots has been done on this, I have a saxo 1.1, had an intimitent problem, where would stall/over rev at idle, also over rev when driving! had a new icv (made it worse) temp sensor (made no difference) and was told needed a new head gasket! Then had the aa for something different and he cleaned a sensor next to the carb and this problem has gone for the last 3 weeks now back again, was wondering what sensor it would have been that he clean and if that should be replaced?

    Thanks
