    can drive around streets all day and it won't go over 90, get on the motorway it goes above 90. Changed waterpump and thermostat and coolant is circulating. Any ideas? Engine code ASZ

    I may be wrong, but I would say head gasket. I had same issue, overheated mainly cruising on motorway or going up hills at lower revs
