keeps cutting out when it gets over half way on the temp gauge. TC light comes on and then it wont start again for about 1 min. If the TC light is on when driving a long(as in faulty) and i floor it the car starts juddering as if the TC is working but there is any need. And while its juddering the engine managment light starts flashing. Then sometimes it cuts out and wont start again. Had on diagnostic at local garage and its showing No problems ANYONE??
