    Default 2.2 dti misfire hesitation on accelaration

    my 2.2 dti has a problem , when i accelarate the car loses power and hesitates, and ecu light comes on for few seconds and goes back to normal before hesitating again, normally happens between 2400 and 3500 rpm, also kangaroo's from standstill on roundabouts, only occasionally though, any ideas anyone, its fine if you drive like a grandad, only when you want to give her some beans it does it
