it is probably by the way you are describing the INJECTOR WARNING LIGHT
Bardh Hoti, January 2011
IT IS THE ENGINE DIAGNOSTIC WARNING LIGHT. YOU NEED TO TAKE THE CAR TO A GARAGE SO THEY CAN CHECK THE E.C.U (COMPUTER) FOR ANY FAULT CODES. THIS WILL COST APPROX £30. IF THEY FIND A FAULT YOU WILL PROBABLY HAVE TO HAVE ONE OF THE ENGINES SENSORS CHANGED.
