Hello Have the following problem with my wife’s car (Ford Ka 2012 gasoline) problem was suddenly jerking at 130 on the AB, power loss and engine control lamp on. Expelsen was error P0300 and P0301. Turn off again was error away. When the car was to the Tüv there was also looking. Ignition coil, spark plugs and ignition cables were renewed and error was gone first. After 2 weeks the same problem again, which strengthened but also with slower drive and in the stand noticed Error P0300 and P0301. Now the car is at Ford. The control unit has checked i.e. ignition coil, candles, cables, i.e. compression to 2 cylinders too low Now they want to control the control times and the valve play. But if it is fixed then nobody knows. Does anyone have experience here or knows themselves?
