Hi Jamie ,

Sorry but no luck with the red light , this question came up at the 3rd Xfire meet & draw a blank , how old & how many miles has your Xfire done , the plugs should be good for about 100k but it could be the age of the plugs .
do you know the service history . i'm sure other will chip in on this subject .
keep an eye out for up & coming meets .


Cheers & Welcome

Andy
