Other common causes: engine stalls

Besides the documented faults of the 1.2 16v, these are the most common causes on any car according to the sources.

  • Clutch technique or worn clutch (manual gearbox)[4]Common
  • Unstable idle: EGR, throttle, mass airflow sensor or air leaks[5][6][7]Common
  • Fuel supply fault: filter, pump or injectors[4][5][8][9]Common
  • Worn spark plugs or coils (petrol)[5]Possible
  • Crankshaft sensor[10]Possible
  • Weak battery or alternator not charging[5][11]Possible

What to check first

  1. Note when it stalls: when releasing the clutch, at idle, when braking or while driving with a loss of power. That detail points to the cause (technique, idle, fuel, sensor or electrical charge).[4][5]
  2. If it is a manual, go over your technique: press the clutch fully down, choose the right gear and release it gradually while you accelerate.[4]
  3. If it stalls on its own, check the battery and the alternator charge: RACE gives a reference voltage of between 13.5 and 14.5 V with the engine running, and warns of dim or flickering lights and of the engine cutting out minutes after starting.[5][11]
  4. Go over the maintenance: filters (air and fuel) according to the manual, cleaning of the intake system and the condition of the vacuum hoses, which may be cracked.[5][9]
