Hey my Vz Calais had been stalling under load the past day so i thought id have a look to see what is wrong. I have only had the car 2 months and done 10,000kms. Here are the pics of the plugs i pulled out.. the car has done 170,000kms and has supposedly has a full logbook history. Has anyone else had this problem of excessive wear? or hadn't they been replaced from factory? Went out straight away and got bosch platnum fusion plugs and it fixed the problem.
