Hello, our 03 V40 1.8 petrol truck has been speeding since yesterday. The car starts normally, runs evenly in idle mode and if you carefully keep the speed running nothing. If you step through a little harder, however, the engine jerks like crazy. What could that be? The camshaft adjuster, as well as timing belts were renewed by Volvo for a lot of money before about 500km. But before the replacement the car ran significantly better and without jerking. Could there be a connection?
