So our opel one day started not giving any recognition to the gas pedal when it went from 1st to 2nd gear for like 3 seconds then it would work like normal. A bit later and now the car stops totaly when it goes from 1st to 2nd and has trouble starting again, any ideeas?? Edit: This happens both on manual and automatic gear, ant the screen that shows what gear you are in says f' or something like that
