the car is a fiat stilo 3dr 2006 1.9Mjtd 110kw all was fine til now. The engine just stall randomly when I change gears ( relace acceleration press the clutch change the gear up and when pressing acceleration again engine is dead now you need to turn off the key and switch the engine back on and is fine) .up like from 5th to 6th or 2 - 3rd it does it so randomly it can be fine for days or weeks and then out of the blue in 3mile das it 3 times. And does not log any error code . Whent to two mechanics and they sad they have no idea what it can be "it cud be any electrical problem"....
