    astra ecu light ...sometimes!!!

    my mk4 astra 1.8 sport runs fine for days then suddenly the ecu light comes on and the car runs like its on on 3 cylinders.limp mode...you run the car for about a mile stop turn the car off take the revs up over 3./400..the ecu light goes out and the car will run fine for another few days....the ecu was changed about 20.000 miles ago..and vauxhall were their usual "no help at all" ..any ideas...
