After many weeks of trying to sort a lumpy tick over and rough running problem i have finally got a fault code,
the code is P1613 Cylinder ! Balance Correction ????
Unfortunatly i have been unable to identify this code, has any one ever had this code before or does anyone know what it means

Thanks M90got Current Stable:
