• Ethanol is less flammable than gasoline, so the ignition problems can occur more easily when using ethanol. In some cars, a slight jerking during the first 5 minutes of driving is normal in cold weather conditions.
  • If the spark plugs or ignition coils are defective or have reached full lifetime, small jerking can occur with a cold engine.
  • If engine warm there should not be jerking with gasoline or with ethanol.

Solution

  • We recommend that the engine be preheated in cold weather conditions. Also when using gasoline.
  • Add a few liters of gasoline to the tank.
  • Replace worn ignition components.
